The project could not be compiled. Would you like to open it in Visual Studio?

I updated my visual studio and this happened when I tried to create a new c++ project using the top down preset.

Hey Snowl0l-

There are some known issues with Visual Studio Update 3 and the engine. You can more information about this here: Build Failed with VS 2015 update 3 - Programming & Scripting - Epic Developer Community Forums - We do hope to include support for Update 3 in a future update to the engine, however for now it would be best to revert back to Update 2.

Cheers

Is there a way to revert back to update 2?

Hey Everyone,

Following the directions in the post by Infected_Post here allowed me to uninstall/reinstall VS2015 Community without Update 3. It does not appear to include a means of obtaining Update 1 or 2, but you should be able to continue using your code projects.

Cheers
