Yeah... I do.
Like I said... it's often buggy & hard to get it to work on a new machine. I've only ever gotten the 32bit version to run & it's not something I can just tell a friend to install with a few clicks. It never just works.

I run the 64 version, no issues (check the howto if you feel like it)
While I do appreciate the link, which might help me get it running on another machine, I am still curious if wine or whatever is needed could all just be shoved into a flatpak kr something. And how much someone might charge to make that happen.
