Fault module : mono.dll

Hello

I recently encountered this problem with Unity 4.2.1.11687 : The application crashes with this error:

Problem Event Name: APPCRASH

I tried performing a clean install of Unity with the latest 4.3 version and I got the same bug , as well as when I tried to install Unity without MonoDevelop.

I am using Windows 7 64 bits and I have a Geforce GTX 275.

I also tried starting Unity while holding the Alt key ( to see whether it is a project-related problem) but still I got the same error , after the "choose your project" window popped up.


Thank you for your time.

 

Update.

I removed Unity with Revo Uninstaller Pro and reinastalled it. Unity worked for a while and then crashed again. Now the error I got was about

Faulty module : ntdll.dll

I founded in the forums that I should add Unity in my DEP exceptions for Windows. I did that, Unity loaded for a minute and then crashed with this error :

Fualty module : LIBPQ.dll

 

Update:

Unity keeps crashing almost every 15 minutes.

A new error message is added to the list:

Fault Module Name: StackHash_e9cd

 

I downgraded Unity to 4.2 and I still get the mono.dll error

I am starting to get desperate...

 

Just try this,

Select unity.exe from program-files/unity.

->left click and select properties.
->change compatibility from Win7 to lower version windows.

Just run again.
I hope it helps.
