Exchange 2013 Setup failed then sits at zero percent when rerunning it

I'm do an install of Exchange 2013 into a forest with an existing Exchange 2010. I plan on migrating my users from Exchange 2010 to Exchange 2013. 

During the original setup of Exchange 2013 I got to step 10 of 14 and Exchange 2013 setup failed because of the Default Search Mailbox. Reading a few articles on the web said to disable the mailbox and then re-run setup. I disabled the mailbox and then restarted Exchange 2013 setup. Setup starts and says:

Incomplete Installation Detected

When I click "next" I get another screen that says "Setup Progress" but it never moves past zero percent. 

Thanks... Frank
