java.io.FileNotFoundException: C:\Users\USER\.AndroidStudio2.1\system\port.lock (Access is denied)

Question

I've already installed the JDK and put it in the right path, now I'm trying to install Android Studio. When it finishes installing, I try to start it, but it returns this message:

I've already done the tick hidden icon and apply and tick again, like the question before, but I still get this error.

Answer 1

In my case, I've hidden the particular user folder by mistake. Unhiding that folder made my Android Studio work normal

Answer 2

though if you are using it as an administrator account it should not have problem,if you using from another account in windows try running as administrator should fix the issue
