I have a utility I've used for 20 years now. Was forced to upgrade to Win7 and ended up with the 64-bit version. Now all my old DOS utilities that I love aren't working. They are D.com and List.com. Both are 16-bit so they won't run. They just kick me instantly to the desktop with a "cannot run that" error. They still work fine in DOSBox, of course, which is where I got the screen caps, below, which shows what they look like. D.com is a color coded directory listing utility, and List.com is a text reader. I still use both of them whenever I'm doing work in cmd.com (and in DOSBox, but no problem there.) I have access to a C++ compiler that can compile 32-bit dos programs, or I can just compile a windows version, maybe, but to do this I need the source code. When I first got them (off a BBS, should tell you how old they are,) they had source code, but I didn't save that. Any help would be appreciated.
