I have a win32 dialog app that I created with vc++ 6.0 and the first time I tried to install it on a computer other than the one that I had C++ on, I had to get Mfc42.dll, Mfc42d.dll, and Mvscrtd.dll and install them in the system directory of the computer before I could use the program. After that it worked fine for computers I was installing it on, but then today I tried to install it on a computer to show someone and it told me that I couldn't use it because I didn't have Mfco42.dll. Is there a way that I can build the program or make a registry key to get around having to have these files, and how can I make it compatible with all OS's: Windows 95/98/ME/2000/NT/XP?
