Can't get Unity to open a project

I just downloaded unity and i wanted to try one of the microgames, however when I try and open it I get a bunch of compiling errors? I’ve tried uninstalling an reinstalling several times now but i keep getting the errors

The issue might not be with Unity installation. Most probably the game project you trying to import/open.

Is there any instruction with the unity project?

Does the project have a specific unity version associated? did you try to open with different unity version than project’s author intended?

and as others mentioned please paste the error log you have.
