I just installed version 2.1.2, but when I opened my project I got this error:

When I click on Install Repository it does not open anything, it does not do anything.

How can I solve it?

It is not good practice to use the "+" sign, if you want to use version 28 you must use Android Studio 3.1.2 as a minimum and to be downloaded you must specify: 

implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'

as currently indicated by the IDE:

but since it is a "beta" version, the recommended thing today (June 2018) is to use: 

implementation 'com.android.support:appcompat-v7:27.1.1'
