Hi all, This is proving great fun. :-( I rebuilt a PC using a NLite OS 1.4 prepared CD. Everything went brilliantly until I tried to view a video file which should have worked in Media Player 9. I found that Media Player was missing but can't remember if this is my fault or not so I tried to install it. Neither Media player version supported e.g. 10 or 11 will install! I get the same error every time not matter what version or how I try to install it:- "This version of Windows Media Technologies is incompatible with this version of Windows. For more information, view the information at the Microsoft web site." This is a nonsense message as I have downloaded compatible versions and it still won't work. Might have to try yet another in place re-install from the original XP SP2 disc just to fix this. Any ideas???
