"Update and Restart" button in android studio 2.1.3 is not working when i try to update it to version 2.2

Question

I received the message for updating android studio to version 2.2 (I'm currently using version 2.1.3 on Windows 7) but when I click on the button "Update & Restart" it does download the patch but when it restarts, it doesn't apply it. I saw an answer to a similar question in this link Android Studio: "Update & Restart" doesn't work but the answer only explains how to handle the issue on Linux while i'm using windows and I don't have any idea how to solve this problem. thank you in advance for your aswers.

I've had the same problem. I just invalidated caches, restarted AS and then updated and it worked for me. File->Invalidate Caches/Restart
