I used to have Caddraw for Windows 3.1. This was a shareware version in 1997 (or even older) and I bought a licence then. This shareware version also worked with Windows XP but not with Windows 7 or 10. It there a replacement that is not too expensive and that can read the MPG files from Caddraw? I still have several drawings on my harddisk but I can't open them anymore. I'm looking for an inexpensive solution.
