Failed to generate code project files VS 2013 installed

Hi, on my pc workstation I have both VS2012 and VS 2013 Ultimate installed on my C: drive.
I need them both and i would not like to uninstall any of them.
I have the following error:

Failed to generate code project files + project name.

On my laptop I’ve installed the same VS configuration (2012 + 2013) and I’ve no problem there with UE4.
I tried lot of things until now, like changing the VS120COMNTOOLS variable, but nothing fixed it.

Has anyone an answer to this?
Thanks

Hi 4thworld,

It looks like some other users experienced a similar issue here:

Why are my code project files failing to generate on VS 2013 Express? - Programming & Scripting - Epic Developer Community Forums

I’m sorry to say that they appeared to resolve by uninstalling and reinstalling VS.

I hope this helps.
