Hi Vic,
It looks like Clearcase VOB is some sort of source code control software. I'm thinking that the files (subVIs) you're using to build your EXE are probably on the network. I am not familiar with Clearcase VOB, but I'm wondering if this source control could be to blame. Have you tried making a copy of the files to your PC and then building the EXE. Does it hang then? Can you narrow down the behavior to determine what files are causing the hang?
Hope this helps!
