i am running window 7rc and my validation key wont work, maybe i copied it wrong , how do I fix this?

Please visit: http://www.microsoft.com/windows/windows-7/download.aspxand click on the download again to view your product key.Carey Frisch

Its not always working to obtain a product key from microsoft from the link you provided. i had one while downloading the 7100 and i have tried it but it didnt work. i had to use the beta 7000 key and it was perfect.It's all about Windows.

As Carey Frisch said, you can just go back to the Windows 7 RC download site and get another one if you didn't copy the first one right. -Nick
