I'm using advanced installer for creating msi package I want copy some files and folders after installation completed to "[APPDIR]" (I know I can do this with add files and folder to files and folder section in advanced installer but I don't want to do that because my files and folder are dynamic in each installation in customer machine)
I write an inline PowerShell script like below
> Param( [string] $source, [string] $dest )
$exclude = #('web.config')
> Get-ChildItem $source -Recurse -Exclude $exclude | Copy-Item
> -Destination {Join-Path $dest $_.FullName.Substring($source.length)}
and in the parameter section, I fill like this "[SourceDir]Project", "[APPDIR]Project"
but it doesn't work. Why?
Abbas has since confirmed that the problem was one of command-line (parameter) syntax:
The parameter section - what to pass to the PowerShell script from Advanced Installer - was filled in as:
"[SourceDir]Project", "[APPDIR]Project" # !! WRONG, due to the comma
whereas it should have been:
"[SourceDir]Project" "[APPDIR]Project" # OK: *space-separated* arguments
Calling scripts/functions/cmdlets in PowerShell works as it does in shells, not as in programming languages; that is, you must separate the arguments being passed with spaces.
By contrast, using , between tokens constructs an array that is passed as a single argument.
From PowerShell run Get-Help about_Command_Syntax for more information.
It depends, you need to give more details. What are the execution settings for your PS custom action?
Have you checked the verbose log to see the params are passed correctly?
Your custom action should be scheduled as deferred with no impersonation, so it is executed after the APPDIR folder is created by the setup package and it has all the rights to write in that location.
Also, you should add rollback and uninstall custom actions to cleanup the files, as during an uninstalled or a canceled/failed installation, those resources will not be cleaned up by Windows Installer.

I have my_project.ps1 file from which I am activating virtual environment & starting my project.
currently I need to open my powershell then after I need to go to directory where I have saved my .ps1 file & have to open it from powershell only.
Is there any way so that I can double click on .ps1 file & it will open automatically in power shell ?
By design, double-clicking (opening) *.ps1 files from the Windows [GUI] shell (in this case: Desktop, File Explorer, and the taskbar, via pinned items) does not execute them - instead they're opened for editing in Notepad or in the PowerShell ISE, depending on the Windows / PowerShell version.
However, since at least Windows 7, the shortcut menu for *.ps1 files contains a Run with PowerShell command, which does invoke the script at hand; this may be enough for your purposes, but this invocation method has limitations - see the bottom section for details.
If you do want to redefine double-clicking / opening so that it executes *.ps1 scripts, you have two options:
Note:
For a given script (as opposed to all .ps1 files), you may alternatively create a shortcut file or batch file that launches it, but that isn't a general solution, as you'd have to create a companion file for each and every .ps1 file you want to run by double-clicking. It does, however, give you full control over the invocation. You can create shortcut files interactively, via File Explorer, as described in this answer, or programmatically, as shown in this answer. Similarly, you may create a companion batch file (.cmd or .bat) that invokes your script, because batch file are executed when double-clicked; e.g., if you place a batch file with the same base name as your .ps1 script in the same directory (e.g., foo.cmd next to foo.ps1), you can call it from your batch file as follows; -NoExit keeps the session open:
#powershell.exe -NoExit -File "%~dpn0.ps1" %*
The methods below also enable direct execution of a .ps1 script from a cmd.exe console window, synchronously, inside the same window. In other words: You can execute, say, script foo.ps1 directly as such, instead of having to use the PowerShell CLI, say, powershell.exe -File foo.ps1
[Not recommended] GUI method:
Use File Explorer to make PowerShell execute .ps1 files by default:
Right-click on a .ps1 file and select Properties.
Click on Change... next to the Opens with: label.
Click on More apps on the bottom of the list and scroll down to Look for another app on this PC
Browse to or paste file path C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe and submit.
This method gives you no control over the specifics of the PowerShell invocation and has major limitations; in effect you'll end up with the following behavior:
Major limitations:
Script paths with embedded spaces and ' chars. cannot be invoked this way, because, even though such paths are passed with double quotes, the latter are in effect stripped by PowerShell, because the path is passed to the implied -Command parameter, which first strips (unescaped) double quotes from the command line before interpreting the result as PowerShell code - in which case paths with spaces are seen as multiple arguments / paths that contain (an odd number of) ' cause a syntax error.
Note that if you were to select pwsh.exe instead, the CLI of the cross-platform, install-on-demand PowerShell (Core) 7+ edition, that problem would not arise, because it defaults to the -File parameter - in which case a double-quoted script-file path is properly recognized.
For the difference between PowerShell CLI calls using -Command vs. those using -File, see this answer.
Passing arguments is not supported, which matters if you want to invoke .ps1 files directly from cmd.exe and need to pass arguments.
The redefinition is only in effect for the current user - which is probably a good thing, as other users may not expect this change, which can result in unwanted execution of scripts.
Whatever execution policy is in effect will be honored; e.g., if Restricted is in effect, invocation will fail altogether.
As with the default Run in PowerShell command, the window in which the script runs will automatically close when the script ends - thus, unless the script explicitly prompts the user before exiting, you may not be able to examine its output.
To exercise more control over how PowerShell invokes the script including support for paths with spaces and for passing arguments, use the programmatic method shown in the next section.
Programmatic method:
Important:
The GUI method overrides a programmatic solution, so it must be removed - the code below does this automatically.
Unfortunately, there's another, accidental override that can happen if you have Visual Studio Code installed: Whenever you use File Explorer's shortcut menu to open a file in Visual Studio Code, it unexpectedly becomes the default action. The code below detects this condition and fixes the problem, but it will resurface the next time a .ps1 file is opened this way.
Modify the registry to redefine the Open shortcut-menu command for *.ps1 files at HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\shell\Open\Command, as shown below.
You can run the code as-is to create a user-level file-type definition that:
uses the executable that runs the current PowerShell session, i.e. powershell.exe in Windows PowerShell, and pwsh.exe in PowerShell (Core) 7+.
respects the effective execution policy - add an -ExecutionPolicy argument to override.
loads the profiles first - add -NoProfile to suppress loading; this is primarily of interest if you're planning to directly invoke .ps1 files from cmd.exe, not (just) from File Explorer, in combination with not using -NoExit.
runs in the script in its own directory
keeps the session open after the script exits - remove -NoExit to exit the session when the script ends; this is primarily of interest if you're planning to directly invoke .ps1 files from cmd.exe, not (just) from File Explorer.
If you requirements differ - if you need different CLI parameters and /or you want to use pwsh.exe, i.e. PowerShell (Core) 7+ instead - tweak the code first, by modifying the $cmd = ... line below; see the comments above it.

Explanation of the predefined Run in PowerShell shortcut-menu command:
It is defined in registry key HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\shell\0\Command (as of Windows 10) as follows:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "-Command" "if((Get-ExecutionPolicy ) -ne 'AllSigned') { Set-ExecutionPolicy -Scope Process Bypass }; & '%1'"
This command is flawed in that it breaks with script-file paths that happen to contain ' characters.
Unless execution policy AllSigned is in effect - in which case only signed scripts can be executed but are executed without prompting - the command attempts to set the execution policy for the invoked process to Bypass, which means that any script can be executed, but only after the user responds to a confirmation prompt beforehand (irrespective of whether the script is signed or not, and whether it was downloaded from the web or not).
At least in earlier Windows 7 releases / PowerShell versions, the command was misdefined[1] in a way that effectively ignored the attempt to set the process' execution policy, which meant that whatever execution policy was persistently configured applied - and no confirmation prompt was shown.
Unless the targeted script explicitly pauses to wait for user input before exiting, the window in which the script will close automatically when the script finishes, so you may not get to see its output.
The targeted script executes in the directory in which it is located as the working directory (current location)
[1] The earlier, broken command definition was "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "-file" "%1" "-Command" "if((Get-ExecutionPolicy ) -ne AllSigned) { Set-ExecutionPolicy -Scope Process Bypass }", which meant what anything after -file "%1" was passed as arguments to file "%1" instead of the intended execution of the commands following -Command; additionally - a moot point - the AllSigned operand would have need to be quoted.
To execute a PS1 file by double-click (to run)
Make a shortcut for the file and set the target to this:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe "C:\Temp\MyPowershellScript.ps1"
Replace the second directory (the one in quotes) with the location of your script.
To read a PS1 file by double-click (to edit)
Same as above, but target ISE instead, as that will force it into edit mode.
C:\Windows\System32\WindowsPowerShell\v1.0\powershell_ise.exe "C:\Temp\MyPowershellScript.ps1"
Server 2012 and newer by default do not associate the .PS1 file extension with the PowerShell executable; rather, they default to open .PS1 files with notepad by default for security reasons.
If you have access, you need to change the file association through the 'default programs' in your control panel for the .PS1 files to execute by double clicking.
Also be aware that you may have to change your execution policy to get particular scripts to run.
Also, as it sounds like this script might be a core automation, you can execute scripts from in another one with either of these, without the need to change the active working directory:
Invoke-Item ""
& ''
I have fixed the registry values so that the .ps1 scripts are executed with double click or with "Run with PowerShell" from any position without problem, even with paths with multiple consecutive spaces and with apostrophes:

I am in the process of writing a custom VSTS extension that (based on parameters) requests a URL and emails the results. I have all pieces of it functioning properly, except the piece that calls PhantomJS exe. This is required in order to generate the screenshot, prior to attaching to the email.
The relevant PowerShell code is as follows:
Write-Verbose "Run phantomjs with $testingurl"
Start-Process -FilePath "phantomjs.exe" -ArgumentList "screenshot.js",$testingurl
$directory = Get-ScriptDirectory
Get-ChildItem $directory -force
I am calling PhantomJS with the relevant parameters, which should create an image in my working directory called 'example.png'. However, when I then output the contents of the directory, the file is not present.
I have played around with the "scope" of my extension, but it has not helped. My current scopes are:
"scopes": [
"vso.build_execute",
"vso.serviceendpoint_manage",
"vso.code_manage",
"vso.packaging_manage",
"vso.release_execute",
"vso.work_write"
],
I also verified that I can create a file if I use the standard PS commandlet:
New-Item "$directory\test.txt" -ItemType file
I also tried including a blank 'example.png' in my VSIX package that would hopefully be overwritten, but it does not.
So, I'm convinced it's not a write-permission issue. The VSTS logs give no indication of the call to PhantomJS exe failing.
Are you not allowed to call an exe from a PS script from within a VSTS extension (build task)? The PS script works correctly locally so I feel this is more of an environment/permission/allowance issue than a code issue on my part.
My issue ended up being that the exe was run and my code continued to execute. I had to add the "-Wait" attribute to my call:
Start-Process -FilePath "phantomjs.exe" -ArgumentList "screenshot.js",$testingurl -Wait
Since the lines following the call to phantomjs.exe requires the execution to finish, the "-Wait" ensures it runs to completion first.
I was going to write up a simple alias 'iis' to invoke the IIS Manager, which is 'C:\Windows\System32\inetsrv\InetMgr.exe'
set-alias iis "OpenIIS.ps1"
and in the OpenIIS.ps1 I have
$item = "C:\Windows\system32\inetsrv\InetMgr.exe"
invoke-item -path $item
This doesn't work. The error I get is "The system cannot find the file specified"
In fact, just doing a Get-ChildItem on the inetsrv won't show the InetMgr.exe (no difference with -Force switch)
Get-ChildItem C:\Windows\system32\inetsrv\*.exe -force
Obviously I can see it in Explorer and I can launch it using cmd, but not with Powershell it seems. Also, Powershell is running as Administrator.
What is going on?
As a workaround I tried creating a link to the file and then invoking that link from Powershell. I now get a 'NotSpecified' Win32Exception.
I have originally used 64 bit Powershell, but get the same result on the x86 Powershell (both run as Administrator)
Are you at the elevated PowerShell prompt? Some system files may not show up unless you use -Force parameter with Get-ChildItem.
I think evidently the file InetMgr.exe is not there as when I do a get-childitem in the mentioned directory,it lists the "InetMgr.exe" there.
This may not be the problem with Get-ChildItem or the Alias you created but instead with ur IIS Server.
When you use a .NET object from PowerShell, and it takes a filename, it always seems to be relative to C:\Windows\System32.
For example:
[IO.File]::WriteAllText('hello.txt', 'Hello World')
...will write C:\Windows\System32\hello.txt, rather than C:\Current\Directory\hello.txt
Why does PowerShell do this? Can this behaviour be changed? If it can't be changed, how do I work around it?
I've tried Resolve-Path, but that only works with files that already exist, and it's far too verbose to be doing all the time.
You can change .net working dir to powershell working dir: [Environment]::CurrentDirectory = (Get-Location -PSProvider FileSystem).ProviderPath
After this line all .net methods like [io.path]::GetFullPath and [IO.File]::WriteAllText will work without problems
The reasons PowerShell doesn't keep the .NET notion of current working directory in sync with PowerShell's notion of the working dir are:
PowerShell working dirs can be in a provider that isn't even file system
based e.g. HKLM:\Software
A single PowerShell process can have
multiple runspaces. Each runspace can be cd`d into a different file
system location. However the .NET/process "working directory" is
essentially a global for the process and wouldn't work for a
scenario where there can be multiple working dirs (one per runspace).
For convenience, I added the following to my prompt function, so that it runs whenever a command finishes:
# Make .NET's current directory follow PowerShell's
# current directory, if possible.
if ($PWD.Provider.Name -eq 'FileSystem') {
[System.IO.Directory]::SetCurrentDirectory($PWD)
}
This is not necessarily a great idea, because it means that some scripts (that assume that the Win32 working directory tracks the PowerShell working directory) will work on my machine, but not necessarily on others.
When you use filenames in .Net methods, the best practice is to use fully-qualified path names. Or use
$pwd\foo.cer
If you do in powershell console from:
C:\> [Environment]::CurrentDirectory
C:\WINDOWS\system32\WindowsPowerShell\v1.0
you can see what folder .net use.
That's probably because PowerShell is running in System32. When you cd to a directory in PowerShell, it doesn't actually change the working directory of powershell.exe.
See:
PowerTip article on syncing the two directories
Channel9 forum thread
I ran into the same problem a long time ago and now I add the following to the beginning of my profile:
# Setup user environment when running session under alternate credentials and
# logged in as a normal user.
if ((Get-PSProvider FileSystem).Home -eq "")
{
Set-Variable HOME $env:USERPROFILE -Force
$env:HOMEDRIVE = Split-Path $HOME -Qualifier
$env:HOMEPATH = Split-Path $HOME -NoQualifier
(Get-PSProvider FileSystem).Home = $HOME
Set-Location $HOME
}
I have a PowerShell script that does some stuff using the script’s current directory. So when inside that directory, running .\script.ps1 works correctly.
Now I want to call that script from a different directory without changing the referencing directory of the script. So I want to call ..\..\dir\script.ps1 and still want that script to behave as it was called from inside its directory.
How do I do that, or how do I modify a script so it can run from any directory?
Do you mean you want the script's own path so you can reference a file next to the script? Try this:
$scriptpath = $MyInvocation.MyCommand.Path
$dir = Split-Path $scriptpath
Write-host "My directory is $dir"
You can get a lot of info from $MyInvocation and its properties.
If you want to reference a file in the current working directory, you can use Resolve-Path or Get-ChildItem:
$filepath = Resolve-Path "somefile.txt"
EDIT (based on comment from OP):
# temporarily change to the correct folder
Push-Location $dir
# do stuff, call ant, etc
# now back to previous directory
Pop-Location
There's probably other ways of achieving something similar using Invoke-Command as well.
There are answers with big number of votes, but when I read your question, I thought you wanted to know the directory where the script is, not that where the script is running. You can get the information with powershell's auto variables
$PSScriptRoot # the directory where the script exists, not the
# target directory the script is running in
$PSCommandPath # the full path of the script
For example, I have a $profile script that finds a Visual Studio solution file and starts it. I wanted to store the full path, once a solution file is started. But I wanted to save the file where the original script exists. So I used $PsScriptRoot.
If you're calling native apps, you need to worry about [Environment]::CurrentDirectory not about PowerShell's $PWD current directory. For various reasons, PowerShell does not set the process' current working directory when you Set-Location or Push-Location, so you need to make sure you do so if you're running applications (or cmdlets) that expect it to be set.
In a script, you can do this:
$CWD = [Environment]::CurrentDirectory
Push-Location $MyInvocation.MyCommand.Path
[Environment]::CurrentDirectory = $PWD
## Your script code calling a native executable
Pop-Location
# Consider whether you really want to set it back:
# What if another runspace has set it in-between calls?
[Environment]::CurrentDirectory = $CWD
There's no foolproof alternative to this. Many of us put a line in our prompt function to set [Environment]::CurrentDirectory ... but that doesn't help you when you're changing the location within a script.
Two notes about the reason why this is not set by PowerShell automatically:
PowerShell can be multi-threaded. You can have multiple Runspaces (see RunspacePool, and the PSThreadJob module) running simultaneously withinin a single process. Each runspace has it's own $PWD present working directory, but there's only one process, and only one Environment.
Even when you're single-threaded, $PWD isn't always a legal CurrentDirectory (you might CD into the registry provider for instance).
If you want to put it into your prompt (which would only run in the main runspace, single-threaded), you need to use:
[Environment]::CurrentDirectory = Get-Location -PSProvider FileSystem
This would work fine.
Push-Location $PSScriptRoot
Write-Host CurrentDirectory $CurDir
I often used the following code to import a module which sit under the same directory as the running script. It will first get the directory from which powershell is running
$currentPath=Split-Path ((Get-Variable
MyInvocation -Scope
0).Value).MyCommand.Path
import-module "$currentPath\sqlps.ps1"
I made a one-liner out of #JohnL's solution:
$MyInvocation.MyCommand.Path | Split-Path | Push-Location
Well I was looking for solution for this for a while, without any scripts just from CLI. This is how I do it xD:
Navigate to folder from which you want to run script (important thing is that you have tab completions)
..\..\dir
Now surround location with double quotes, and inside them add cd, so we could invoke another instance of powershell.
"cd ..\..\dir"
Add another command to run script separated by ;, with is a command separator in powershell
"cd ..\..\dir\; script.ps1"
Finally Run it with another instance of powershell
start powershell "cd..\..\dir\; script.ps1"
This will open new powershell window, go to ..\..\dir, run script.ps1 and close window.
Note that ";" just separates commands, like you typed them one by one, if first fails second will run and next after, and next after... If you wanna keep new powershell window open you add -noexit in passed command . Note that I first navigate to desired folder so I could use tab completions (you couldn't in double quotes).
start powershell "-noexit cd..\..\dir\; script.ps1"
Use double quotes "" so you could pass directories with spaces in names e.g.,
start powershell "-noexit cd '..\..\my dir'; script.ps1"
