Depending upon the usage there are two solutions to your problem.

First.

  1. Close the TeamViewer application.
  2. Open the start menu. Go to the Run dialogue box and type “%appdata%”.
  3. Search for the TeamViewer folder and delete all of its files and folders.
  4. If you are using Wi-Fi, try changing the IPv4 address of your computer.
  5. Now restart your computer and start the TeamViewer application once more.

Second (Windows 7 or Vista users)

  1. Turn off the User Access Controls (UAC)
  2. Now run the command called “msconfig” from the Run dialogue box.
  3. A dialogue box will appear. Under the Tools tab, look out for a button to ON/OFF UAC. Switch this button to appropriate position.

Now restart your system and try running the TeamViewer application.

If you are using a computer from your office and you want to connect to your computer at home, that’s possible with TeamViewer. To do that, first, both computers should have TeamViewer installed and second, the TeamViewer application should be running on both machines. If the TeamViewer application is not running on the other computer, you will not be able to establish connection.

Also, make sure your computer meets the requirements to run the application. TeamViewer supports Windows XP, Windows Vista, Windows 7, Windows 8.x, and Windows 10. For servers, it supports Windows Server 2003, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, and Windows Server 2012 R2. If you haven’t updated yet to the latest version, download TeamViewer 12.

You can also try TeamViewer Portable. TeamViewer is a remote PC control and sharing tool that allows you to remotely control a partner’s computer to provide online assistance.
