No compiler was found problem

i re installed unreal and now it says that i must install visual studio but i already got that installed from the first time. Should i just re install studio or is there a box in some option menu somewhere that i need to click?

Take a look at those threads: https://answers.unrealengine.com/search.html?q=No+compiler+was+found+&type=question&lang=en&sort=relevance :slight_smile:

e.g

" The easiest attempt is to try to repair your install, such that the registry information gets up to date."

Just reinstalling studio and running once seemed to work fine.
