General

Yes, TeamViewer is compatible with UAC and works automatically on operating systems with User Account Control (UAC).

With Windows Vista, Microsoft introduced UAC, which leads to a password prompt, whenever administrative activities are being performed. This is an additional security feature of Microsoft Windows.

When connecting to a remote device, this could lead to issues in regards to being to able to perform administrative activities on the remote device in the following case:

  • The remote computer is logged in with a non-admin account when connecting to a full version or Host on the remote device AND a non-installed version of TeamViewer is running (e.g. portable version, run-only full version, QuickSupport module).

Please follow the steps below on troubleshooting UAC for connections to a TeamViewer Host or full version or to a TeamViewer Service Case or to the TeamViewer QuickSupport:

UAC for connections to the TeamViewer Host or full version

To avoid UAC issues during connections via a TeamViewer ID when connecting to the TeamViewer Host or full version (when the remote computer is logged in with a non-admin account) please do one of the following:

  • If not already done beforehand: Install the TeamViewer full version or Host on the remote computer.
  • Run the TeamViewer software on the remote device with administrative rights (for TeamViewer run-only full version, Portable, or QuickSupport module).

  • Connect to the remote device using TeamViewer ID and Windows Authentication instead of the password. This requires the Windows account credentials of an admin account on the remote device.connect-with-windows-credentials.pngConnect to a Windows device with the Windows login credentials.

UAC for connections to a TeamViewer Service Case

To avoid UAC issues during connections to a Service Case (session code), please connect to the service case using Windows Authentication instead of the password.

This requires the Windows account credentials of an admin account on the device that created the service case.connect-to-a-service-case-and-uac.pngConnect to a service case using Windows login credentials.

UAC for connections to the QuickSupport module

If you are connecting to a customer running a QuickSupport module, there are a few additional steps needed in order to interact with remote UAC prompts.

Please see below for the steps required in order to interact with the UAC prompt on a remote machine when connected to a TeamViewer QuickSupport:

    1. Start TeamViewer on your computer
    2. Ask your partner to start TeamViewer QuickSupport on their device
    3. Ask your partner for their TeamViewer ID shown in TeamViewer QuickSupport 
    4. Select the option Remote support and enter your partner's TeamViewer ID in the field Partner ID
    5. Click on Connect to Partner

Hint: If you are using QuickSupport with Session codes (Service Cases), after your partner starts TeamViewer QuickSupport on their device, select Remote Control using Windows authentication to the right of the service case in your Computers & Contacts window. See chapter above.

The TeamViewer dialogue will open, but as you are connecting to a QuickSupport module, a new message also appears.

Hint: When you click Log On please be advised you will not be automatically connected. You will see a new message appear at the bottom of the TeamViewer application window:qs4.png

The remote computer will be prompted with a UAC prompt from TeamViewer. Instruct the remote user to select YES to allow TeamViewer to make the requested changes.

Once the user accepts the UAC prompt, their TeamViewer QuickSupport will restart. Reconnect to the ID, and you will be prompted with the Windows credentials login screen again. Re-enter the local admin credentials, and you will be connected to the device.

You are now connected to your partner’s computer and can control the UAC as you wish.
