If Vegas 9 (latest) is installed on a system already running Vegas 8 (final), will they coexist happily (or will the new one overwrite shared files or registry settings etc. relied upon by the old one, risking side-effects) ?
I have Vegas 8 32bit and Vegas 9 64bit installed side-by-side without any issues.
When I lose my media/timeline in Vegas 9 64bit, I can actually load up Vegas 8 32bit to restore the media associations which fixes the issue in Vegas 9 64bit!
the real problem arises when they get divorced and one walks out of the system. instead of taking the record collection, it takes what used to be your shared plugins....
