I created a script to uninstall an application silently from the reg keys. It's worked for a few different apps without an issue. I'm trying to uninstall brave browser but, I keep getting this error below. I think the reason is because the uninstall string for brave is
C:\Program Files\BraveSoftware\Brave-Browser\Application\95.1.31.91\Installer\setup.exe" --uninstall --system-level.
The --uninstall and --system-level may be causing the error and I'm not to sure how to get around it.
Any ideas are greatly appreciated.
Error Message Below
Start-Process : This command cannot be run due to the error: The system cannot find the file specified.

It's kind of a pain, but you need to parse the command from the arguments somehow. Also the silent install option might not be '/S'. I think I've seen '--force-uninstall'. It's easier with msi installs. You can just use uninstall-package.
$uninstallstring = '"C:\Program Files\BraveSoftware\Brave-Browser\Application\95.1.31.91\Installer\setup.exe" --uninstall --system-level'
$split = -split $uninstallstring
& (-join $split[0..1]) $split[2] $split[3]
Note that you can get the uninstallstring from get-package too.
$uninstallstring = get-package *brave* | % { $_.metadata['uninstallstring'] }

I'm currently trying to setup a script to uninstall Chrome from PCs to upload onto Intune but following the MS documentation on the parameters of new job triggers just pops up with errors on invalid times. I'll paste below the documentation I'm using to get the parameters, not sure where to go in terms of resolving the error
https://learn.microsoft.com/en-us/powershell/module/psscheduledjob/new-jobtrigger?view=powershell-5.1
Register-ScheduledJob -Trigger $Trigger -RunAs32 -ScriptBlock {
$SEARCH = 'chrome$'
$INSTALLED = Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, UninstallString
$INSTALLED += Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, UninstallString
$RESULT = $INSTALLED | ?{ $_.DisplayName -ne $null } | Where-Object {$_.DisplayName -match $SEARCH }
if ($RESULT.uninstallstring -like "msiexec*") {
$ARGS=(($RESULT.UninstallString -split ' ')[1] -replace '/I','/X ') + ' /q'
Start-Process msiexec.exe -ArgumentList $ARGS -Wait
} else {
$UNINSTALL_COMMAND=(($RESULT.UninstallString -split '\"')[1])
$UNINSTALL_ARGS=(($RESULT.UninstallString -split '\"')[2]) + ' --force-uninstall'
Start-Process $UNINSTALL_COMMAND -ArgumentList $UNINSTALL_ARGS -Wait
}
} -Name RemoveChrome```
I'm moving a yaml pipeline so it uses PS Core. One of the steps is to parse currently installed software and uninstall it if it exists:
$appsToUninstall = Get-Package -Provider Programs -IncludeWindowsInstaller -name "*$Instance*"
if ($appsToUninstall.count -gt 0)
{
Get-Service | Where-Object { $_.Name -match "$Instance" } | Stop-Service
$appsToUninstall | Uninstall-Package -Force -Verbose
Write-Output "Uninstalled $Instance"
}
else
{
Write-Warning "Nothing to uninstall! Could not locate $Instance as an installed instance. Continuing as usual."
}
However, it would seem that the new Get-Package - no longer provides installed software.
Is there any way to use native cmdlets (not CMI/WMI [wmi is deprecated!]) to achieve that in the new PS 7+?
You can parse the registry to achieve this :
$Instance = "MyAppToUninstall"
# Initialize array to avoid errors on 32 bits applications addition
[array]$appsToUninstall = #()
# Get 64 bits programs
$appsToUninstall = Get-ItemProperty `
HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* |
Select DisplayName, UninstallString |
Where { $_.DisplayName -like "*$Instance*" }
# Add 32 bits programs
$appsToUninstall += Get-ItemProperty `
HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* |
Select DisplayName, UninstallString |
Where { $_.DisplayName -like "*$Instance*" }
if ($appsToUninstall.count -gt 0)
{
Get-Service | Where-Object { $_.Name -match "$Instance" } | Stop-Service
$appsToUninstall | ForEach-Object {
$app = $_.UninstallString.Substring(0, $_.UninstallString.IndexOf(".exe") + 4)
$arguments = $_.UninstallString.Substring($_.Uninstallstring.IndexOf(".exe") + 5)
if ($app -match "(?i)msiexec")
{
# if MSI package, replace /i parameter by /x to uninstall and
# add /passive parameter to automate the uninstallation
$arguments = "$($arguments.Replace("/I", "/x", [system.StringComparison]::InvariantCultureIgnoreCase)) /passive"
}
Start-Process -FilePath $app -ArgumentList $arguments
}
Write-Output "Uninstalled $Instance"
}
else
{
Write-Warning "Nothing to uninstall! Could not locate $Instance as an installed instance. Continuing as usual."
}
I hope this helps :)
I can uninstall NVIDIA Graphics Driver from PowerShell but I am unable to figure out how to do it silently. The normal code looks like this:
#Get Uninstall String from Registry
$us = Get-childItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" -ErrorAction SilentlyContinue | Get-ItemProperty | Where-Object {$_.DisplayName -like "*NVIDIA Graphics Driver*"} | select DisplayName, UninstallString
# Splitting the Uninstall String into executable and argument list
$unused, $filePath, $argList = $us.UninstallString -split '"', 3
# Any of the following command can start the process
Start-Process -FilePath "C:\Windows\SysWOW64\RunDll32.EXE" -ArgumentList $argList -Wait
# or
Start-Process $filePath $argList -Wait
Once the process is started it displays the NVIDIA Uninstaller dialog box for manual selection/click of the UNINSTALL button to proceed further.
My UninstallString looks like:
"C:\Windows\SysWOW64\RunDll32.EXE" "C:\Program Files\NVIDIA Corporation\Installer2\InstallerCore\NVI2.DLL",UninstallPackage Display.Driver
I have tried following ways but nothing seems to work.
Start-Process -FilePath "C:\Windows\SysWOW64\RunDll32.EXE" -ArgumentList "/X $argList /quiet" -Wait
Start-Process $filePath -ArgumentList $argList "/S" -Wait
Please guide me, how to do silent uninstallation.
To summarize the comments into an answer:
#Get Uninstall String from Registry
$us = Get-childItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" -ErrorAction SilentlyContinue | Get-ItemProperty | Where-Object {$_.DisplayName -like "*NVIDIA Graphics Driver*"} | select DisplayName, UninstallString
# Splitting the Uninstall String into executable and argument list
$unused, $filePath, $argList = $us.UninstallString -split '"', 3
# Append arguments for silent uninstall
# -deviceinitiated avoids a system restart
$argList += ' -silent -deviceinitiated'
# Any of the following command can start the process
Start-Process -FilePath "C:\Windows\SysWOW64\RunDll32.EXE" -ArgumentList $argList -Wait
The key is to add any arguments intended for rundll32.exe to the $argList string.
i tried to uninstall puppet-agent-x64 silently used this command:
$registryPath = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", "HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {
$_.displayName -eq "Puppet Agent (64-bit)"
} | Select-Object -Property UninstallString
$uninstall = $registryPath.UninstallString
& cmd /c $uninstall /qn /norestart
and one can still finding the program under appwiz.cpl
Any hence please!
How do I take a first command output?
I Want to take the IdentifyingNumber.
I Have tried this following command:
$app = Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -Like "App"}
$getNumber = $app[1]
OutPut:
IdentifyingNumber : {00000-00000-0000-000000000}
Name : App
Vendor : App
Version : 1.0.0
Caption : App, Inc.
Technically if you're putting [1] it selects the second object in the array as they start at [0] so if you wanted the first one do $var = $app[0].IdentifyingNumber
i have created this following scrip and it's worked so well, thank's for all, if i help someone this is the script.
$Keys = Get-ChildItem "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"
foreach ($subkey in $Keys) {
if($subkey.Name -notmatch "InstallWIX_"){
Set-Location -Path $subkey.PSPath
$app1 = Get-ItemProperty -Path ".\" | Where-Object displayname -Match "app1"
$app2 = Get-ItemProperty -Path ".\" | Where-Object displayname -Match "app2"
$GUID_APP1 = $app1.PSChildName
$GUID_APP2 = $app2.PSChildName
if ($app1.Displayname -eq "APP1") {
& cmd /c msiexec.exe /x $GUID_APP1 /qn /norestart
} elseif ($app2.Displayname -eq "APP2") {
& cmd /c msiexec.exe /x $GUID_APP2 /qn /norestart
}
}
}
