I'm going to guess that your new computer came with Windows 10. I discovered that I had to leave a few programs behind when I migrated from Windows 7 to 10.
If you still have a full copy of Windows 7 you could wipe the new system and install Windows 7. I was still able to run most of my Win XP era programs just fine on Win 7. Not so much with Win 10, although I think that Win actually 10 performs better. Progress!
