Try this ,

1) open cmd with Run as administrator

2) type: netsh winsock reset

3) restart computer

After restart open Android Studio and check for errors if no errors all fine!

else try the following:

2. Disabled UAC ( User access Controls in windows)
3. Updated to the latest Java Version
4. Reinstalled Android Studio
5. Update windows if you are on it.

1. Go to folder where android-studio is installed. (e.g. C:\Program Files (x86)\Android\android-studio)

2. Now go up one folder. (i.e. C:\Program Files (x86)\Android)

3. Right click on the android-studio folder and go to Properties.

4. In the Properties window, go to the Security tab.

5. Click the Edit button.

6. A new window will open, here you click the Users (your-username-or-your-group-name)

7. From the list below, check Allow in front of Full control.
