I wonder if this is the same thing some others are having. Where the backup works but when the program goes to close itself it crashes, thankfully after the backup and only when trying to close itself.
Are you able to run the program manually just fine? And I have seen this on every version of Windows but haven't been able to replicate it.
I think it has something to do with the controls on the window of the program, the people who have it crash have it set to run silently and not show itself, if you have it set to run silent try changing it to run shown and see if it still crashes and let me know. I just need to trace down the part that is crashing and get it fixed
