I was struggling to get Unit Testing support in #develop 2.0 today (via the unit tester addin), (http://community.sharpdevelop.net), and noticed a few issues with the installer.
First of all there's no feedback: the installer appears to "load," but then vanishes. It actually does an installation and everything, but it took several minutes of searching (and me launching the installer 2 or 3 times) before I realized that it installed MbUnit to my Program Files directory. Second of all, it doesn't register any of its important assemblies to the gac, which means cut-and-pasting the relevant DLLs to the target directory or registering the assemblies by hand. Both methods suck. ;)
