Does it crash always or occasionally?
I would say "always". I tried it 3 times in a row and then now another 2 times and it crashed all 5 times. Obviously the number of tries is very small, but at least I would say the crashes are very frequent. Can anyone else beside MIP try it on Windows? I didn't change anything in my OS since the previous version I had (which was 1.1.6.9b).
I'm running 1175 on prod and three instances on testnet also 1175. No issues. windows 10 64-bit pro. 
I can reproduce crash on windows 10 64-bit home. application starts then just exits. so, this may be specific to windows 10 64-bit home, as I can't reproduce on win 10 64-bit pro.
