Problem description: 
Application launch hangs closes approximately 1/3rd of the way through the program load for both 3.5.5 and 3.6.4 on Windows XP and W7 platforms. I have tried reducing removing add-ins and install options to a minimum. I have also fully uninstalled both apps multiple times. The application log entry for the current platform (W7) is:-
