Visual Studio missing includes

So I’m doing a fairly simple project of room escape and everytime i have to use something out of the ordinary i have to make an include to be able to use it as seen in the screenshots. I probably messed up the instalation but would rather not have to reinstall everything as i’m using a metered connection anything i can do about it?

Also nothing seems to work now since i reopened visual studio. Most of the errors seem to be syntax related but one of them is slightly more worrying:

name followed by ‘::’ must be a class or namespace name

EDIT: I’m currently doing an install repair on vs

it is exactly this… Thank you very much i was getting very fustrated :slight_smile:

Room escape? This sounds like the Udemy tutorial. Are you sure you are not having this problem? <3
