Invoke-Command doesn't launch the executable on a remote workstation - powershell

Question

I'm trying to uninstall MS Office 2007 on all workstations in my Active Directory. For this, I have to launch C:\Transfer2007\setup.exe which is configured by the UninstallConfig.xml file for a silent uninstallation (located in the same directory). PowerShell's Invoke-Command doesn't return any errors and it seems as everything is fine, but the setup.exe never launches on the target workstation.
When I launch the setup.exe manually, I get the 'Open File - Security Warning' where I have to press 'Launch'. In the next step, I get asked for administrator access (UAC). I think these popups are the problem as to why the .exe never launches when trying to run it remotely through PowerShell.
I already tried to include the following in the code:
–ExecutionPolicy Bypass
-Credential parameter with admin rights
UninstallationConfig.xml file:
<Configuration Product="ProPlus">
<Display Level="none" CompletionNotice="no" />
<SettingId="SETUP_REBOOT" Value="AutoAlways" />
</Configuration>
PowerShell code:
Invoke-Command -ScriptBlock {
Set-Location "C:\Transfer2007\";
.\SETUP.exe /uninstall ProPlus /config \UninstallConfig.xml
} -Credential mmb -ComputerName $Computer -AsJob

Answer 1

Try execute this ScriptBlock
$app = Get-WmiObject -Class Win32_Product |
Where-Object {$_.Name -match "Office"}
$app.Uninstall()
OR
Invoke-Command -ComputerName server01 -ScriptBlock {
Start-Process 'C:\Transfer2007\SETUP.exe' -ArgumentList '/uninstall ProPlus /config \UninstallConfig.xml' -Wait
} -Credential (Get-Credential 'localhost\Administrator') -ComputerName $Computer -AsJob
