GP vbs Logon Script

I have a vbs logon script that is supposed to run a few exe’s if their corresponding apps are not installed (Asset mgmt, AV and SW Dep tool)

When I manually run the code from within XP and W2k and it performs as expected. The executables are run and applications are installed.

But when running the same code as my logon script, the applications are not installed.

Help would be greatly appreciated.
