Progress Bar Frozen

I need a progress bar to show movement while executing a process that takes a couple of minutes. I don't need to show an accurate representation of status, but just movement. It worked fine with Application.Sleep, but when I implemented my actual EXE that runs, it froze until the exe finished. I presume the "Wait for Exit" is what is holding that up.

The bar can even be one that completes multiple times. Any ideas gang?
