@Andy BB2 overwrites the installation of BB1. I had to re-install BB1 into a different directory, because at this moment I want to be able to use both versions. Is it possible to choose a different installation directory when installing BB2 (just like it is possible for BB1)? At this moment it is not possible.
The installer is bypassing the option to install in a different location, we should have this resolved in the next release.
