I've got a .ps1 script that I use to open a new instance of powershell as a different user:
runas /netonly /user:******\******* powershell
Until today it worked fine but now it returns the following error:
Attempting to start powershell as user "*******\********" ...
RUNAS ERROR: Unable to run - powershell
2: The system cannot find the file specified.
Has anyone else encountered this error before, are there any known fixes?
OP here: Solved this, didn't realise that I had accidentally overwritten a PATH Local Environment Variable. For future poor souls like me, the fix is:
System Properties -> Advanced Tab -> Environment Variables -> System Variables:Path -> add C:\windows\system32\WindowsPowerShell\v1.0
I'm sure there is a better solution however

Whenever I open Windows Powershell I see this
powershell error message. It seems to me that every time I open Powershell it attempts to run conda.exe from a TEMP folder that no longer exists on my machine. Furthermore, when I open command prompt I see this error, so I'm guessing it's doing the same thing there.
I've checked my user and system path variables and there is no mention of the temp path that is listed in the powershell error. Any help with this would be greatly appreciated!
When such a thing happens, it's most likely because of your PowerShell $Profile, that is always loaded on startup.
Check the file, see if it exists and what's inside it. If you still got issues after that, let us know.
All,
Note: I have updated the question after some feedback.
Thanks to #jisaak for his help so far.
I have the need to run a PowerShell script that adds TCP bindings and some other stuff when I deploy my Cloud Service.
Here is my Cloud Service Project:
Here is my Cloud Service Project and Webrole project:
Here is my task in ServiceDefinition.csdef:
And here is the PowerShell script I want to run:
here is my attempt at the Startup.cmd:
When I deploy I get this in the Azure log:
And this in the powershell log:
Any help would be very much appreciated.
I think I am nearly there but following other people syntax on the web doesn't seem to get me there.
thanks

I think the issue is that the working directory of the batch command interpreter when it runs Startup.cmd runs is not as expected.
The Startup.cmd is located in the \approot\bin\Startup directory but the working directory is \approot\bin.
Therefore the command .\RoleStartup.ps1 is not able to find the RoleStartup.ps1 as it is looking in the bin directory not in the bin\Startup directory.
Solutions I know to this are:
Solution 1:
Use ..\Startup\RoleStartup.ps1 to call the RoleStartup.ps1 from Startup.cmd.
Soltuion 2:
Change the current working directory in Startup.cmd so that the relative path .\RoleStartup.ps1 is found. I do this by CHDIR %~dp0 (see here) to change into the directory that contains Startup.cmd.
Solution 3:
As Don Lockhart's answer suggested, do not copy the Startup directory to the output, instead leave it set as "Content" in the Visual Studio project. This means the files within it will exist in the \approot\Startup directory on the Azure instance. (You would then want to make sure that the Startup folder is not publically accessible via IIS!). Then update the reference to Startup.cmd in ServiceDefinition.csdef to ..\Startup\Startup.cmd, and update the reference to RoleStartup.ps1 in Startup.cmd to ..\Startup\RoleStartup.ps1. This works on the fact that the working directory is bin and uses ..\Startup to always locate the Startup directory relative to it.
You don't need to set the executionpolicy within your cmd - just call the script. Also, you should use a relative path because you can't rely that there is C disk.
Change your batch to:
powershell -executionpolicy unrestricted -file .\RoleStartup.ps1
Right click on the RoleStartup.ps1 and Startup.cmdin Visual Studio and ensure that the Copy to Output directory is set to copy always.
If this still doesn't work, remove the startup call in your csdef, deploy the service, rdp into it and try to invoke the script by yourself to retrieve any errors.
Edit:
Try to adopt your script as below:
Import-Module WebAdministration
$site = $null
do # gets the first website until the result is not $null
{
$site = Get-WebSite | select -first 1
Sleep 1
}
until ($site)
# get the appcmd path
$appcmd = Join-Path ([System.Environment]::GetFolderPath('System')) 'inetsrv\appcmd.exe'
# ensure the appcmd.exe is present
if (-not (Test-Path $appcmd))
{
throw "appcmd.exe not found in '$appcmd'"
}
# The rest of your script ....
I've found it easier in the past to not copy the content to the output directory. I have approot\bin as the working directory. My startUp task element's commandLine attribute uses a relative reference to the .cmd file like so:
The .cmd file references the PowerShell script relatively from the working directory as well:
PowerShell -ExecutionPolicy Unrestricted -f ..\StartUp\RoleStartup.ps1
Ok,
So I am coming back to this after many different attempts to make it work.
I have tried using:
Startup config in the ServiceDefinition.csdef
I have tried registering a scheduled task on the server that scans the Windows Azure log looking for [System[Provider[#Name='Windows Azure Runtime 2.6.0.0'] and EventID=10004]]
Nothing worked either due to security or the timing of events and IIS not being fully setup yet.
So I finally bit the bullet and used my Webrole.cs => public override bool OnStart() method:
Combined with this in the ServiceDefinition.csdef:
Now it all works. This was not the most satisfying result as some of the other ways to do it felt more elegant. Also, many others posted that they got the other ways of doing it to work. Maybe I would have got there eventually but my time was restricted.

I have a Jenkins (1.493) project that uses the Jenkins PowerShell build step to execute a PowerShell script. Inside that script I want to invoke another script that is stored inside a file. I have now reduced it to the following:
Script inside Jenkins PowerShell build step:
& "\\stemmer.local\sidevelopment\cvdev\devbase\jenkins\PowerShell\Test.ps1"
Content of Test.ps1:
write-host 'Hello world!'
Whenever this Jenkins project executes, the PowerShell build step hangs indefinitely.
Things I have tried/verified so far:
Adding some output before the invocation of Test.ps1 shows me that the Jenkins PowerShell script is being execute normally up to the point where Test.ps1 is called.
The file Test.ps1 exists and is reachable from the build slave that executes the script. If I alter the file's name, I get the expected error message from PowerShell...
Exchanging the " for ' in the 1st script does not change anything. Also, using dot-sourcing rather than & does not help.
The file Test.ps1 can be executed properly from the powershell itself using the same command line that is being used in the Jenkins PowerShell script.
The execution policy for PowerShell has been set to unrestricted on my development host as well as on the Jenkins build slave.
I've tried replacing the PowerShell build step with a Windows batch command build step that looks like this:powershell.exe -InputFormat None -File "\\stemmer.local\sidevelopment\cvdev\devbase\jenkins\PowerShell\Test.ps1"and played around a little with the parameters of powershell.exe, but the results were - in those cases that were syntactically and otherwise correct as far as I can tell - always the same.
I only found few references to problems that sounded similar, but none of the approaches mentioned elsewhere did help me fix this. I am absolutely puzzled, and wondering whether someone encountered this issue before (and maybe even got a scenario like the one I have in mind running).
Thanks a lot for any input!

have you tried to set execution policy to bypass ?
Copy the script file locally, then invoke it from within the Jenkins PowerShell plugin - that way it works as expected.
I got some strange behaviour when executing a powershell script.
When I run my script using the ISE it works just fine.
When I open Powershell.exe and run my script it works just fine.
When I open cmd, and start my script using powershell.exe -noexit
./myscript.ps1, myscript works just fine.
When I double-click myscript however, powershell opens for some milliseconds, I see that it shows some error (red font) and the powershell window closes. I'm unable to track down the error causing this problem since the powershell windows closes to fast.
I even tried one single big try-catch block around my hole script, catching any [Exception] and writing it down to a log file. However: the log file is not generated (catch is not called).
How can I track that issue? What could possibly be causing the trouble?
Please note that my execution-policy is set to unrestricted.
Before trying the suggestion invoke this to see your current settings (if you want restore them later):
cmd /c FType Microsoft.PowerShellScript.1
Then invoke this (note that you will change how your scripts are invoked "from explorer" by this):
cmd /c #"
FType Microsoft.PowerShellScript.1=$PSHOME\powershell.exe -NoExit . "'%1'" %*
"#
Then double-click the script, it should not exit, -NoExit does the trick. See your error messages and solve the problems.
But now all your scripts invoked "from explorer" keep their console opened. You may then
remove -NoExit from the above command and run it again or restore your
original settings.
Some details and one good way to invoke scripts in PS v2 is here.
Unfortunately it is broken in PS v3 - submitted issue.
by default, for security reason when you double clic on a .ps1 file the action is : Edit file, not Run file .
to execute your script : right-click on it and choose run with powershell
I also wasn’t able to run a script by double clicking it although running it manually worked without a problem. I have found out that the problem was in the path. When I ran a script from a path that contained spaces, such as:
C:\Users\john doe\Documents\Sample.ps1
The scipt failed to run. Moving the script to:
C:\Scripts\Sample.ps1
Which has no spaces, solved the problem.
This is most likely an issue with your local Execution Policy.
By default, Powershell is configured to NOT run scripts that are unsigned (even local ones). If you've not signed your scripts, then changing your default double-click 'action' in Windows will have no effect - Powershell will open, read the execution policy, check the script's signature, and finding none, will abort with an error.
In Powershell:
Help about_execution_policies
gives you all the gory details, as well as ways to allow unsigned scripts to run (within reason - you'd probably not want to run remote ones, only ones you've saved onto the system).
EDIT: I see at the tail end of your question that you've set Execution Policy to 'unrestricted' which SHOULD allow the script to run. However, this might be useful info for others running into execution policy issues.
If you would catch the error you will most likely see this
The file cannot be loaded. The file is not
digitally signed. The script will not execute on the system. Please
see "Get-Help about_signing" for more details.
Because you are able to run it from the shell you started yourself, and not with the right mouse button click "Run With PowerShell", I bet you have x64 system. Manually you are starting the one version of PowerShell where execution policy is configured, while with the right click the other version of the PowerShell is started.
Try to start both version x64 and x86 version and check for security policies in each
Get-ExecutionPolicy
I was in exactly the same situation as described in the question : my script worked everywhere except when double-clicking.* When I double-clicked a powershell windows would open but then it will close after a second or so. My execution-policy is also set to unrestricted.
I tried the selected answer concerning FType Microsoft.PowerShellScript.1 but it didn't change anything.
The only solution I found was a work around: create a bat file which start the powershell.
Create a file, copy this and modify the path : powershell.exe -File "C:\Users\user\script\myscript.ps1"
Save it as a .bat
Double-click the bat
I also used .ahk to start my powershell with a shorcut and it didn't work when pointing directly to the powershell. I had to point to the .bat
I have an MSBuild script that I want to call from a PowerShell script as part of a deployment process. If I call the build script via a bat file all works well. If I do the exact same thing in PowerShell I get CS1668 error looking for wierd and wonderful paths that dont exist on my machine.
I know I am getting into the MSBuild script as these errors are occuring from within the MSBuild script targets (logging output is showing this).
The bat file and the PowerShell script reside in the same place, right next to the build script.
Errors:
error CS1668 : Warning as error :
Invalid search path 'C:\Program
Files\Microsoft Visual Studio
8\VC\AtlMfc\Lib' specified in 'LIB
environment variable' -- 'The system
cannot find the path specified. '
error CS1668 : Warning as error :
Invalid search path 'C:\Program
Files\Microsoft Visual Studio
8\VC\PlatformSDK\Lib' specified in
'LIB environment variable'-- 'The
system cannot find the path specified.
'
I have checked and neiter of these paths do NOT exist on my machine.
Why would running from PowerShell change what paths MSBuild look for?
Thanks in advance

EDIT- adding in code: NB the name of the MSBuild script is AutomatedDebug.build
POWERSHELL SCRIPT:
#Begining of script
$CurrentPath = Split-Path (Split-Path $myinvocation.mycommand.path )
#Assign the Build script paths. 1 is for building and testsing, 1 is for deployment (to keep things clean)
$MSBuildScriptBuildAndTestPath = $CurrentPath + "\Tools\AutomatedDebug.build"
$MSBuildScriptDeployPath = $CurrentPath + "\Tools\Deploy.build"
#Run the automated build with tests
Write-Host "*** Run the automated build with tests ***"
C:\Windows\Microsoft.NET\Framework\v3.5\MSbuild.exe $MSBuildScriptBuildAndTestPath "/t:AllTests" "/l:FileLogger,Microsoft.Build.Engine;logfile=AllTests.log"
if($LastExitCode -ne 0)
{
throw "AllTests failed"
}
Write-Host "*** FINISHED: Run the automated build with tests ***"
Bat File
#C:\Windows\Microsoft.NET\Framework\v3.5\MSbuild.exe AutomatedDebug.build /t:AllTests /l:FileLogger,Microsoft.Build.Engine;logfile="AllTests.log"

Ok, what is actually happening is that I have dowloaded the Powershell Community Extensions (http://pscx.codeplex.com) many moons ago and there is a Environment.VisualStudio2005.ps1 file in there that adds EnvVars that dont exist. This is (I assume) becuase i dont use VS2005. I have commmented this out and all is well. I have tried to look for the 2008 equivilent but dint have too much luck. To be honest i dont use powershell to its full potential so i doubt i even need the PSCX on my machine anyway.
Thanks guys for your help.
It is most likely due to how you are passing parameters into the MSBuild script. There are some key parameter parsing differences between CMD and PowerShell and by using a batch file, you are implicitly using CMD's parameter parsing engine to hand off the parameters to MSBuild. If you post the command line you're using, one of the PowerShell gurus here can probably help debug where the parameters are getting confused.
I am wondering, basically you get "Warning as error" here. You can either try turning off treating warnings as errors (I mean, having a lib path which doesn't exist doesn't sound that bad to me) or you'll let your scripts print out the respective environment variables (using echo %LIB% and $Env:LIB respectively) from the scripts and look for differences.
However, since the envvars for VS aren't set globally by default (that's why there are the three Visual Studio command prompts) you have to set all variables somewhere. If you're doing this within the scripts you may have a typo somewhere?
