We’ve had to occasionally run this tool to uninstall Screenconnect if someone wiped the original setup.msi package. Does anyone have any powershell that can use this tool against a known software? We can get the package name, etc. from powershell using wmi, etc. just need to run the tool to do whatever it does.

I don’t know how well it will work generally, but this is what I figured out for fixing broken ScreenConnect agents that won’t upgrade:
$name = "ScreenConnect Client (b7fb61blahblahblah)"
Get-ChildItem "HKLM:\SOFTWARE\Classes\Installer\Products\*\" | Get-ItemProperty | Where-Object ProductName -like "$name" | Remove-Item -Recurse -Force
Get-ChildItem "HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\" | Get-ItemProperty | Where-Object DisplayName -like "$name" | Remove-Item -Recurse -Force
