I had a scanner that wouldnt work on a 64 bit machine at all even with a vitural machine windows xp. I've forgotten any details about it but the orignal drivers were not available online even for sale. vuescan could make it run on a 32 bit only machine running windows 98SE I think. I sold it on ebay for $9.
I remembered!
Acer 2720s, last update to its driver was in 2001 for XP. Benq bought the company and they didnt even know what it was when I contacted the technical department in 2013.
Sometimes the technical stuff just becomes obsolete and hard to make it work.
