Looks like I was correct. I did some research and found a comment by Peter Gannon about just this issue:

The old installers will put many files in BB folder. Then the user should manually run the cleanup routine again. Either run the bb_cleanup.exe from the bb\data folder or from the help-utilities- menu in BB

They also plan further modifications to make this easier in the future.
