c# app can not run because mscoree.dll not found

Nov 30 2006 2:18 PM
I wrote a simple helloWorld c# app, it ran OK on one PC running XP sp2. But it can not run on another PC running XP without p2 or sp1, and it also can not run on my windows2000, the error message saying "The dynamic link library mscoree.dll could not be found in the specified path G:\documents and settings\... ... " How can I fix it so that c# applications can be run across all XP versions, and window2000?
