What is your overall mission for this? Are you trying to find if office 2007 is installed and if it isn't install it? Or trying to label computers that don't have it installed by vbs?
If it's the first one you should do the whole lot in vbs and then the job should always be a success UNLESS an unknown error occured.
So should be something like (didnt check this for errors just typed it in):
dim filesys
dim WSHShell
Set filesys = CreateObject("Scripting.FileSystemObject")
Set WSHShell = WScript.CreateObject("WScript.Shell")
If not filesys.FolderExists("C:\Program Files\Microsoft Office\Office12\") Then
WSHShell.Run "C:\Office Install.msi"
WSHShell.quit(0)
else
WSHShell.quit(1)
End If
Now this will check whether office 2007 is installed and if not install will install it and return and error level of 0. This will give you a green tick in DS. If it is installed it will give you an error level of 1 which in DS will give you the red cross. Or you can change the errorlevel codes in DS to what you want. This is done by double clicking on the job and going to the last page of the job setup. Add your errorlevel and your return text and whether it complete or failed or should go to next job.
