Hi, found the problem. Vista for some reason dosnt register VBScript. What you have to do is first of all find where vbscript.dll is, mine was in C:\Windows\System32, but I think it changes dependant on your version. Next you need to go to start -> accessories and the right click on command prompt and click "run as administrator", next type "cd C:\Windows\System32" (replace the dir if its differnt for you) and then type "regsvr32 vbscript.dll". It should then confirm that vbscript has been registered and everything should work. This will fix a few installs, i found the same problem with itunes as well.
Hope this helps,
Cheers,
James
