Windows 8.1 Update Ruins Unity

I tried it again and again, and the same error appears.

I am using the 4.5.1f3

 

Has anybody found a solution for this problem? Any build I send to windows 8.1 crashes on startup, giving an error about a break at KERNALBASE.exe .... the proposed -force-d3d11 and -force-opengl doesn't do a thing. Running in compatability mode doesn't do a thing. The game works fine when opened on my windows 7 machine.

This problem persists even if I build for x86 or x86_64.

Built from: Unity 4.3.4f1
Built for: Windows x86 and x86_64

Successfully built and ran on:
Intel Core Duo, 4gb ram, Radeon 4670 gpu, Windows 7 64bit ultimate

Crash problem on:
Intel i7 CPU, 8gb ram, NVidia GeForce GT 735M(best driver found, published 8/30/2013), Windows 8.1 64bit (fresh upgrade 6/23/14)

 

The current version of the Web Player that is available from our website is 4.3.5f1 It shouldn't update if you are downloading it from the site http://unity3d.com/webplayer

 

I downloaded from there as you suggested and always the same. Before Windows 8.1 everything worked fine. I'm thinking about format and go back to windows 8...
