According to your hiatus, any databases you might still have are from 2003 or earlier, or maybe as late as 2007. If you have any from version 97 you won't be able to open those at all with the newer/newest versions. Last one for that is 2007 I think. Since you can only have 1 version on a drive label AFAIK, best to consider that. Could also have 2 or more swappable disks or partitions with separate boot partitions or separate pc's and have the old and the new. I think 2019 is the latest version, but you could probably do well with anything 2010 and up. In fact, why not get back in with a cheaper used version and then upgrade if you find that you stick with it and need it? You should compare version features to see if there are any that you can't do without. IMO, 32 bit install is the way to go.
