vb shell will not launch unless its under and admin acct

I have a vbshell that I wrote and it will not launch unless its under an admin acct on windows xp. I can not figure out why

Here is the code for the script

Set shell = CreateObject(“WScript.Shell”)
shell.Run “PsExec.exe -a 1 C:\Pathways\WFMGR\wfmgr.exe”
WScript.Quit

Thanks,
Mark
