Bootwiz.exe not starting when creating Preboot Environments

I'm running Altiris Suite 7.1 SP2 MP1.  Whenever I try to create or recreate a Preboot Environment, Bootwiz.exe is not starting up.  I was able to create a PXE Preboot before and it appears in the images folder.  Now whenever I try to create something, Altiris Console tells me it exists but the files don't appear anywhere on my server.  Has anyone run into this before?  I've attempted several other solutions I found in the Symantec forums but nothing has worked so far.  

Thanks!
