siliconman01 wroteBuild 780 program crash logs on Windows 7 x64 Professional. Uninstalled previous build prior to installing Build 780.
This debug information was very interesting! According to the Debug Log, the problem is not that the program crashes when started. The problem is that the program closes automatically when started, and the crash occurs when the program closes (which is a Known Issue).
In other words, there are currently two issues:
1. The Initial Setup freezing, and
2. The program automatically closing / crashing when started.
Here is an updated beta build:

This build attempts to fix the problem you experience (issue number 2), and it also contains some more debug code in order to help me to fix the other problem (issue number 1).
So please download it, and let me know how it works. If either of the problems still persist, please send over the Debug Log and bugreport.txt
