How can I install and enable a themepack for another user in Windows 7?

[Guest Erik78]

I'd like to write a powwershell script to set a Theme (.themepack-File) for all the users on my system. I already did this successfully in Windows XP, but cannot make it run in Windows 7. The problem is that the Theme is later available for the other user, but not activated. When I try to set the theme for a user that is currently logged on, it works flawlessly of course. Here is what I do in my scrupt, the $cred variable already contains the user credentials required. I run this script as an addministrator user from another user account.

 

$args = "/K "

$args += "`"$env:MYTESTPATH\themes\Touch-Win7.themepack`""

 

$cred = Get-CredentialMachineUser

$proc = start-process -PassThru -LoadUserProfile -cred $Cred -ArgumentList $args $env:SystemRoot\System32\cmd.exe

 

When I run this script, I get a messagebox, probably from the Windwos 7 Thememanager containing the following error message:

 

**[Window Title]

::{26EE0668-A00A-44D7-9371-BEB064C98683}\1\::{ED834ED6-4B5A-4BFE-8F11-A626DCB6A921},?Theme=C%3A%5CUsers%5Cmachine%5CAppData%5CLocal%5CMicrosoft%5CWindows%5CThemes%.theme

Do you have any idea what's going wrong, and how I can enable a themepack successfully for another user?
