I am trying to install Windows 2000 Upgrade (w SP1) into a PC with NT4 & Svc Pk 6a. Within the first minute and before actually starting anything, I get an error message stating the installer "..cannot determine the version of Windows.." and exits immediately. I've tried this in VGA mode, Off Line with same results. I need the info quickly. Any ideas or cures?

This may be an software problem that can be worked around Open Regedit and locate the HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion
the thing to do is change the version to another version other than 4.0 and then try to install.

While the website is chock full of info, none of it directly addresses my problem. I tried the CD in another PC since posting the question, and it works fine.

Have you tried upgrading Windows 2000 without the Service Pack 1 initially? I would also try reinstalling Service Pack 6a on the Windows NT 4 server.

Yeah, I tried all that. In the end I found an answer: the person who installed the NT 4 workstation neglected to put all the letters "oem" in the serial number- apparently it took it that way, therefore the numeric count of the length of the s/n was low and Win2K upgrade rejected it.
