Considering how Orbiter is such a simple program to install, and doesn't write to the registry or scatter files all over your system; Just keep multiple installs going. I have done that with 2006-p1, and intend to keep it installed for a while while I migrate over to 2010. I'm sure some add-ons won't work. And other will be updated and improved over time. There's just so much you can do with this simulator that keeping multiple installs is really a trivial matter.
I've got installs from 900mb all the way to 6gb. With terabyte hard disks, I don't see a problem!
