Software Deployment

Hey guys,

This is my first post here and i am hoping that other members can share their expertise and help me out here. I have been given tasks of deploying and uninstalling few applications via GPO. Deploying was not an issue after i got my hands on a msi file. I am having a lot of pain uninstalling winzip (7, exe) and winrar (3.20, exe) installed. Now, these software needs to be removed. I have browsed previous posts here and tried to use those as well but so far no luck.

I am using a Win2000 domain environment. No option to schedule tasks. Users on WIN XP Pro SP2/SP3.

I was told to create a silent login script that would uninstall these applications to all users when they log into the domain. So, GPO -> login script.

What i have tried:
1. I tried calling winzip32.exe /uninstallx and uninstall.exe /s (for winrar)
-> For WINZIP, works well but needs local admin credentials. For normal user who does not have elevated rights, they receive the message "Cannot uninstall - file C:\program files\winzip\readme.txt is in use by another program. Same thing shappens with WinRAR uninstall as well.

Even tried the VBS below i found online, same result for WinZIP uninstall.


On Error Resume Next
Dim fso
Set fso = CreateObject("Scripting.FileSystemObject")
main()
sub main()
'Let's find out where WinZip is installed
WZPath=regget("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\winzip32.exe\")
Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.Run WZPath & " /uninstallx",0,TRUE
FullWZPath = replace(WZPath, "PROGRA~1", "Program Files")
DeleteAFolder(left(FullWZPath,(len(FullWZPath)-13)))
end sub
function regget(value)
on error resume next
Set regedit = CreateObject("WScript.Shell")
regget=regedit.RegRead(value)
end function
function DeleteAFolder(filespec)
Dim fso
on error resume next
Set fso = CreateObject("Scripting.FileSystemObject")
fso.DeleteFolder(filespec)
end function


2. Since this needs to be a silent uninstall, the RUN AS command is not an option.
3. Tried the CPAU command to pass username and password and execute a script, it says it completed successfully but it doesn't uninstall the program.

Please help! how can i get this done. I don't know what i can do anymore.
