Are you installing the creator with ADMIN rights.
Note Do NOT plug in your Miniprog3 until all software installation is complete AND the PSoC Creator application has been opened.
I'm experiencing exactly the same problem, which is dragging at least from Creator 4.0, according to similar crash reports in this forum. I also have Windows 10, latest update, and Visual Studio 2017 in the same machine. A rather common scenario I guess. I tried the repair tips suggested in a couple of posts without any success. Also noticed the following.
1) If I load Creator alone, side by side with Visual Studio, I can leave both running overnight without crashing.
2) If I load a sample project without major modifications, it seems to hold on without crashing.
3) As long as my project works in complexity and move over to Visual Studio to test some piece of code, Creator silently quits without warning or saving edited files or the environment. You loose everything.
4) It seems that one thing that triggers this is when I try to add the printf() over a UART, which I have to remove anyway because in a 32KB Flash 42xxx device consumes all remaining Flash and it can't compile.
