What the heck did i do wrong?.. please help. I dont know what the heck to do.

is Visual Studio 2015 installed with the common tools?

Visual studio 2015 is infact installed (as of now, i read that actually in a different forum. How would i go about actually installing the common tools?)

hello

download the Visual Studio community, open it and select “modify”.

A lot of options will show up to select, you select the common tools and install it, it is about 2GB

Good luck

Hi fillipe, thank you a lot for the help. I actually got confused for a second and launched the application thinking i would find the common tools there. Haha, i was going nuts looking for it.

Needless to say i found it. Thank you!
