Unity 5.5 - mscorlib.dll is an invalid CIL image

Scripting C# & .NET
1

Hi :slight_smile: I’m developing my game with Unity for a while. I upgraded from Unity 5.3.5(64-bit) to Unity 5.5.0f3(64-bit). It worked fine on my cheap laptop with Windows 8 and on my Mac Mini but on my main pc that I use to develop games, Unity 5.5 throws the error “The file C:\Program Files\Unity\Editor\Data\MonoBleedingEdge\lib/mscorlib.dll is an invalid CIL image” regardless of the project or scene. I opened a new project, when I add a script to the project result is the same. I reinstalled Unity 5.5 numerous of times, uninstalled and reinstalled .NET 3.5, have VS 2015 and .NET 4.6 installed on my pc. I tried to copy MonoBleedingEdge folder from 5.4.0, that didn’t helped either. Please note that I use Windows 7 SP1 64-bit.

I liked Unity 5.5 as my game run faster on some cheap android, please help me to find the error with Unity 5.5 :slight_smile:

I shipped my game with Unity 5.4.3. Using Unity 5.6 for my new game. Version 5.6 seem to work fine. It’s ok for me.
