I am trying to upgrade from WIn XP home to Win XP Pro. I am getting these 2 errors:

                Windows XP Upgrade Compatibility

The option to upgrade will not be available at this time because Setup was unable to load the file
D:\i386\WINNTUPG\NETUPGRD.DLL.

%1 is not a valid Win32 application.

Setup information file D:\i386\COMPDATA\NTCOMPAT.INF is invalid.

Contact your system administrator.


I have used this disk before as well it works fine...

Did you disconnect all external peripherals except the monitor, keyboard and mouse, and be sure those are not USB, or wireless.  Any internal USB card should also be removed.

I got my copy from Microsoft MSDNAA website and it says...Microsoft WIndows XP Professional Single User Copy...

I've never tried a upgrade install using a OEM disc, but it could be that it will not upgrade.
