Installer fails to register behaviors


I found the installer fails to register the behaviors to Blend.
And I checked out the source code and reviewed the setup projects.
Then I found these behaviors are registered to Blend by adding 2 the registery keys.
Then I verified these 2 registery keys, and I found the path is wrong formatted.
My path in registery is looked like this "C:\Program Files\Physics Helper\Physics Helper Library\WP7"
So I guess this issue might be caused because setup project process the target folder in a lazy way, which doesn't deal with the tailer slash well.
