Hi @shock66, it is generally a good idea to use a separate install, but I get the impression that most people don't bother, which isn't usually a problem. It's just a good idea to have a backup of your LaunchBox folder available, just in case, at all times. In my case, I use Dropbox which pretty much solves any potential risks. For what it's worth, I use all the betas for my own personal collection, and I've yet to have to restore anything, but I also have a backup ready at all times.
