I’m pretty sure I’d run Windows 10 64bit and virtualize a 32bit “machine” to run the old stuff before I installed 32bit on bare metal. Especially given how transparent something like VMware Fusion is on a mac w/ Unity… Virtual PC, windows containers, vmware… I’m sure there’s a better solution. Better to run the host OS at 64bit with full power and use that for things you can leverage 64B for… and the 32bit VM isn’t going to suffer much from virtualization - it’ll suffer from being memory cramped regardless.
You can’t run these apps on dos/WOW? Are you truly running DOS or just old windows? (Windows 95? XP)?
I realize this is OT and probably more political/policy than technical, it’s just really surprising to me.
