Using result of test-path to execute powershell command - powershell

Looking to execute a powershell command that will uninstall an application and clear some registry entries if either a file/folder is not present on the system.
Currently looking at something like this:
if(!(test-path “c:\Windows\mdm” )
{
$productdetails=(Get-WmiObject -Query “Select IdentifyingNumber from win32_product where name = ‘Tesapp’“).identifyingnumber
$proc=(Start-Process -FilePath “msiexec.exe” -ArgumentList “/x $productdetails /qn /l*v c:\temp\Uninstall-testapp.log” -Wait -PassThru).ExitCode
if (!($proc -eq 0 -or $proc -eq 3010))
{
exit(1)
}
$RegKey=“HKLM:\SOFTWARE\Microsoft\TestAppManagement\S-0-0-00-0000000000-0000000000-000000000-000\MSI\{0}” -f $productdetails
if(test-path $RegKey)
{
$op= Get-Item $RegKey | Out-File “c:\windows\temp\TestApp_Reg_backup.reg” -Force
$op= Remove-Item $RegKey -Force
}
}
Interestingly if I run the test path it will return false which is expected, or if run the app uninstall/reg clear on its own it will work as intended - however i cannot run them together.
I assume i am making some sort of syntax/ basic logic error?

Powershell Onedrive uninstall script, file not found

I'm trying to make a powershell script to uninstall Onedrive from users computers by running Invoke-Command -computername computer1 -filepath script.ps1
but i keep getting issues with the last step.
The first function "doUninstall" works just fine, it runs it and so on.
But the second one "douninstall2" doesnt work, it cant run the file
Anyone have any ideas what im doing wrong and how to fix this?
When i try running it using
Start-Process -filepath $UninstallCommand -ArgumentList "$EXEArgumente" -Wait
I can see the process starting on the target computer but it closes immediately

PowerShell Script - Run multiple executables in parallel and wait for all launched executables to terminate before proceeding

I have an executable file (.exe) which has to be run multiple times with different arguments in parallel (ideally on different cores) from a PowerShell script, and at the end wait for all launched executables to terminate. To implement that in my PowerShell script I have used the Start-Job command that runs multiple threads in parallel. And as the script needs to wait for all jobs to finish their execution I used Start-Job in the combination with Get-Job | Wait-Job. This makes the script wait for all of the jobs running in the session to finish:
$SCRIPT_PATH = "path/to/Program.exe"
$jobs = Get-ChildItem -Path $DIR | Foreach-Object {
if ($_ -like "Folder") {
# Do nothing
}
else {
$ARG1_VAR = "Directory\$($_.BaseName)"
$ARG2_VAR = "Directory\$($_.BaseName)\SubDirectory"
$ARG3_VAR = "Directory\$($_.BaseName)\SubSubDirectory"
if (Test-Path -Path $ARG1_VAR)
{
Start-Job -Name -ScriptBlock {
& $using:SCRIPT_PATH -arg1 $using:ARG1_VAR -arg2 $using:ARG2_VAR
}
}
else
{
Start-Job -Name -ScriptBlock {
& $using:SCRIPT_PATH -arg1 $using:ARG1_VAR -arg3 $using:ARG3_VAR
}
}
}
}
$jobs | Receive-Job -Wait -AutoRemoveJob
However, it seems that -FilePath argument of Start-Job does NOT accept .exe files, but only .ps1 files, and therefore I get an exception.
Thus, I decided to use Start-Process command instead which spawns seperate processes instead of seperate threads. But I was not able to find a command that can wait for the termination of all started processed from my script. Therefore, I tried to do it manually by storing all started processes in an array list. And then I tried to wait for each process (using process ID) to terminate. However, that does not seem to work either, because Start-Process -FilePath Program.exe -ArgumentList $ARG_LIST returns NULL, and therefore nothing is saved in the $Process_List.
$SCRIPT_PATH = "path/to/Program.exe"
$procs = Get-ChildItem -Path $DIR | Foreach-Object {
if ($_ -like "Folder") {
# Do nothing
}
else {
$ARG1_VAR = "Directory\$($_.BaseName)"
$ARG2_VAR = "Directory\$($_.BaseName)\SubDirectory"
$ARG3_VAR = "Directory\$($_.BaseName)\SubSubDirectory"
if (Test-Path -Path $ARG1_VAR)
{
$ARG_LIST = #( "-arg1 $ARG1_VAR", "-arg2 $ARG2_VAR")
Start-Process -FilePath $SCRIPT_PATH -ArgumentList $ARG_LIST -PassThru -NoNewWindow
}
else
{
$ARG_LIST = #( "-arg1 $ARG1_VAR", "-arg3 $ARG3_VAR")
Start-Process -FilePath $SCRIPT_PATH -ArgumentList $ARG_LIST -PassThru -NoNewWindow
}
}
}
$procs | Wait-Process
I would appreciate any help. Please note I am using Powershell 5.1, thus ForEach-Object -Parallelconstruct is not supported on my machine.
Thank you!
Regarding your first example with Start-Job, instead of using the -FilePath parameter you could use the -ScriptBlock parameter:
$path = 'path/to/my.exe'
$jobs = Get-ChildItem -Path $DIR | Foreach-Object {
Start-Job -ScriptBlock {
& $using:path -arg1 $using:_ -arg2 $using:ARG2_VAR
}
}
$jobs | Receive-Job -Wait -AutoRemoveJob
Regarding your second example, using Start-Process you should note that, this cmdlet produces no output without the -PassThru switch, hence you're adding effectively nothing to your list.
$processes = Get-ChildItem -Path $DIR | Foreach-Object {
Start-Process -FilePath Program.exe -ArgumentList $ARG_LIST -PassThru
}
With this minor addition of the -PassThru switch you can either use a while loop checking the .HasExited Property of the objects in case you need to do something else with your code while waiting for the processes:
# block the thread until all processes have finished
while($processes.HasExited -contains $false) {
# do something else here if needed
Start-Sleep -Milliseconds 200
}
Or even simpler, as mklement0 points out, if you only need to wait for the processes, you can use Wait-Process:
$processes | Wait-Process

Power Shell Get Service Issue

Hi I need to get a script that will do the following:
Check if a service exists
If the service doesn't exist run my script
If the service exists do nothing
Here is what I have but it's not working for me:
$service = Get-WmiObject -Class Win32_Service -Filter "Name='servicename'"
if($service.Status -eq $NULL)
{
$CLID = $inclid
New-Item -Path "c:\" -Name "folder" -ItemType "directory"
Invoke-WebRequest -Uri https://something.com\setup.exe -OutFile c:\folder\swibm#$CLID#101518#.exe
$installer = "swibm#$CLID#101518#.exe"
Start-Process -FilePath $installer -WorkingDirectory "C:\folder"
}
else
{
Write-Host "Client Already Installed"
}
If I run $service.Status alone I get an "OK" returned. Under this condition I would need the script to stop and run the else section. I only want this script to run if $service.Status returns nothing. Where am I going wrong here?
You may try putting $null on the left hand side of the comparison.
If($null -eq $services.status)
Here is a nice write up discussing it
Simpler way to check if service exists:
if( Get-WmiObject -Class Win32_Service -Filter "Name='servicename'" ) {
# Service exists
}
else {
# Service doesn't exist
}
... or use the Get-Service cmdlet:
if( Get-Service -ErrorAction SilentlyContinue -Name servicename ) {
# Service exists
}
else {
# Service doesn't exist
}

Unable to run PowerShell uninstall script

I am trying to start a process and wait for the exit code. The process starts msiexec with an argument list. When i run my script it comes up with the argument help wizard, however if i run the command directly in CMD generated by:
write-host $command
It works as expected. Here is my full script:
# Get uninstall strings from registry, looking for the msiexec option
$applist = Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall |
Get-ItemProperty |
Where-Object {$_.DisplayName -match "Microsoft Visio Standard 2013" -and $_.UninstallString -match "msiexec"} |
Select-Object -Property DisplayName, UninstallString
# Check for any aplications requiring uninstall and output their names
if ($applist) {
foreach ($app in $applist) {
Write-host "$($app.DisplayName) has been detected for uninstall"
}
Write-host "Attempting to uninstall application(s)"
# Uninstall each application that has been identified
foreach ($app in $applist) {
try {
$uninst = $app.UninstallString
$pos = $uninst.IndexOf(" ")
$leftPart = $uninst.Substring(0, $pos)
$rightPart = $uninst.Substring($pos+1)
$command = """$rightPart /qn /L*V ""C:\UninstallVisio.txt"""""
write-host $command
$uninstall = (Start-Process "msiexec.exe" -ArgumentList $command -Wait -Passthru).ExitCode
if($uninstall.ExitCode -ne 0) {
write-host "attempting XML config uninstall"
#**still to be worked on**
}
} catch {
write-host "Unable to uninstall $_.Name Please view logs"
Continue
}
}
}
Exit
# Exit script as no apps to uninstall
else {
write-host "No application(s) detected for uninstall"
Exit
}
Instead of this
$command = "$uninst /qn /L*V ""C:\UninstallVisio.txt"""
try
$command = #(
$uninst
"/qn"
"/L*V"
'"C:\UninstallVisio.txt"'
)

Continue
}

}
#Exit script as no apps to uninstall

It looks like you are trying to run msiexec.exe with ArgumentList "msiexec.exe /x {ProductCode}".
Powershell is trying to run your command as "msiexec.exe msiexec.exe /x {ProductCode}"
