So I made a program, and have thoroughly tested the bugs out, and now finally figured out how to make a release build for my grandfather to see. So he tries running it and it crashes on the first input. I was told i may need to send him the run time or statically link something? I am confused. Can some1 shed some light?

Does the program run ok in release mode on your computer?

Ya, i tested it on a VM too, think grandfather maybe having problems.
