Can't compile project's anymore

My VS did an update and now I can no longer compile in unreal engine, even if I create a brand new project I get an error saying “Unhandled exception for the gamemodebase .gen .cpp .json version “1.2” isn’t supported”

Having the same issue. This is being caused each time Visual Studio is updated.

Deleting the intermediate folder and regenerating the visual studio project files will fix the issue until you try to compile more than once. Each time the project compiles, the generated version will update, rebreaking it.

Hi @SalmonLemur29,
There is a patch to the source code awaiting consideration see
Unhandled exception when building blank project: Version (“1.2”) is not supported version - Unreal Engine / Programming & Scripting - Unreal Engine Forums

The patch was created by another person all I have done is make it easier to install

$ git pull origin pull/9067/head:UEvs2200
