I had to reload MSCS and MSIB on my development PC.  After removing and
reinstalling MSIB, when I tried to unpack MSIB21.pup, it complains that the
MSIB21 and MSIB21admin applications already exist.  I've tried to remove
them (no doubt, the wrong way) by deleting the directories from IIS and the
databases from SQL Server, but I'm still getting the same error.

How do I clean this up, so that I will have a clean install?

Any help is appreciated.
