Hey Guys,

I just received my beta copy of Longhorn, and when I attempt to install, I get this error:

"An unknown command line option and was specified."

Did anyone get this error upon install? How do I fix? I was going to copy the disk to another CD, but I wanted to know your thoughts. Thanks.

Hello,

I had the same problem when running Longhorn 4074 from the hard drve [sATA].

I just went into 'Sources' and clicked on 'Setup.exe'.

Hope this helps!
