I have an enterprise version of office 2007 on DVD, which was ordered
directly from Microsoft. when I try to install it by running
"setup.exe" I get this error:

D:\outlookr.WW\Osetup.DLL digital signature does not validate or is
not present

Since Microsoft doesn't mention this anywhere on their website and
technical support costs $200, I'm really hoping that someone reading
this can help me.

I've tried everything i can think of:
-- running setup from the command prompt
-- copying all the files to my hard drive then running setup

If anyone out there knows any way to overcome this issue, I'd
appreciate you filling me in.

Thanks!!
