Windows 11? It's a miracle they got it running on 10. I might have a little time on my hands and I do have a complete copy of this program on a port HD somewhere. I would love to figure out how these folks got it to run on 10. I would forget 11 if nothing more than it gets so many changes and patches overriding programs security particuarly Alldata with the dongle crap becomes more of a moving target.
