It means I have tried to install it somewhere between 3-5 times.
Whenever I start it, it goes...

So, essentially Windows is telling me that brackets is no longer working whereas what it means is it never did... for me.
Well, it kinda does, when I go through the program compatibility assistant.
At some point it even finds some configuration to have it start.
But then it doesn't actually remember whatever settings worked, even though it asks me if it should.
So, next startup I am again greeted with the above.
FWIW:
windows 8.1 — crashes on startup
Best wishes, Tobias.
