I think it may be due to the fact that I installed an old version of Xamarin, and then got my new license and installed the newest one. Should I reinstall Xamarin maybe? I really want to start coding after getting my new license
If you need more clues just answer and I'll be quick to answer!
Edit: Forgot to mention that the paths in the Visual Studio settings are correctly set and already were, I have checked and the data is there (NDK, JDK, etc)
The registries are dumb it seems.
