Is it possible you were running windows 10 in 32 bit just for the software? When I had my pc built with win seven I was told I could do that in 10 somehow for my older version of SL, 8.1 like you. As it is just a pc for work station I opted for probably the very last dell ever built with 7 lol. I still think your problem could be the 64 bit vs 32 bit butting heads. I got a dollar says if you pay cadlink the 75 bucks they simply tell you to give up 425 more to upgrade giving you credit for the tech charge. Than again they might wnat the whole 575, lol.
That would be handled in the compatibility layer, which the OP said ran it in several. The only contention would be if there were specific SP mode that needed to be done (typically this was more for the XP compatibility mode, but it may affect others as well). Otherwise, dlls are loaded dynamically as needed, rather it's for 64 or 32 bit.
Have to realize that this is Win 11, other things could have been pulled or changed that would make a change to even from 10 to 11 go from working to not working.
As much as people like to think, can't really always expect a piece of software built to run on previous versions of Windows to always run on the latest and greatest, despite the amount of legacy bloat that helps with that.
The question that I have to wonder, is all of these rhapsodies worth it compared to just upgrading to something that will more than likely work on newer hardware (or go the VM route or get a legacy box)?
