PianoMonk My XP machines are strictly off line, and I've gutted most of the Microsoft bloat to make them run better. Although, the XP bloat isn't nearly as bad as newer systems, especially the 64bit stuff. Anyway, when I got the original Finale 2009 and Sibelius 6, I created an ISO file for each and saved them to both CD's and a backup drive. So, even when I've changed a hard drive, or built an entirely different PC, I can re-install them. I got in the habit of making ISO's of almost everything, games, apps, etc., back in my I.T. days. Kind of geeky, I know.
There's the advantage of being knowledgeable and being able to tweak things because you know how. Everything you wrote makes sense. I'm still a dinosaur about IT matters. I hate the way things have been going, with subscriptions, updates that come automatically that add unnecessary bells and whistles - sometimes it impacts my work at an inopportune moment. But that's getting away from the topic at hand.
If I had an extra machine that I could keep off-line and a bunch of other things that would be perfect. I purchased Finale at a time when you got it from the site, and reinstall it from the site. I have a bare working knowledge of Finale, haven't created macros or anything. It makes sense for me to transition, but not for you and others who know it inside out and aren't caught out be anything Internet-wise / new computer-wise in the future.
I appreciate all the insights.
