The question is a simple one. I have a program on disc which runs on the old Windows 7 machine after I did something to make it work. I can Install it on this machine, but for the life of me, I cannot remember what I did to make it run before. Tried opening it in Compatability mode, but nothing seems to work. Each time I start it up, all it does is Re-instal itself, then will not work. Previously, it had to install each time to work and it did that and made a Restore point on the computer, then it ran ok. Any suggestions?
It must have been fairly simple as I did it without any reference to anyone else or any books etc. 4 years ago though, so no memory of it.
