Yes, Turbo C does work on Windows 7 but only on the 32 bit version. Turbo C is a 16-bit program and unfortunately, Microsoft dropped 16-bit application support for Windows 7 64-bit. However, there are many ways to make it work on the 64-bit version. Before going into the details, I would to advice every beginner that Turbo C is not a good IDE and it is very outdated by today's standards. You may start with it but don't stick to it for a long time. The sooner you look into other IDEs the better it is!
