"Fatal app exception" while Mission Planner launch

Hello,

I updatet my local Mission Planner Software to latest 1.3.7.
Unfortunately the software doesn’t start anymore. (screenshot)
As mentioned in another post, I have already deleted the config.xml, but no effect.
Also the newest DirectX Driver is insatalled on my System.

I tried to unisnstall MP and install my old 1.3.5 again,
but it doesn’t start anymore, even though it works perfectly before that.

I am working on Windows 7 .

Are there any recommendations or steps to get MP running?

I have exactly the same problem and error output in the console. Windows 7 64-bit as well. Updated the MP up to 1.3.70 and it doesn’t work anymore. Reinstalled it and it still doesn’t work :frowning:

Update:
Solved the problem by updating .Net:
