I've been a lifelong Linux user, and this makes me sad.

I don't know enough to comment about whether or not it's necessary, but any time I've tried to get anything working that wasn't updated recently, it was impossible.

Well impossible is a bit strong, the process ranges from:

- Find a forum post that links to some old .deb files and install them manually

- Install a newer version of a dependency and then recompile from source code, after spending an hour or two updating the program so it works with the new version of the dependency because the dependency changed its API for no reason (that one's not a Linux problem per se, but it wouldn't be necessary if the old one still worked!)

Better to download the Windows version and run it in WINE...
