# Activating TeamViewer on the MiSeq i100 Series Instruments
**Background**
The TeamViewer application is built into the instrument Control Software, allowing Illumina to provide remote support to users once activated. After remote support has concluded, the user can disable TeamViewer, preventing unauthorized remote access.
*Enabling TeamViewer in the Control Software*
1. From the MiSeq i100 Control Software, select the drop down menu in the top left corner, then select **Support**.
2. On the Remote Support user interface (UI), select **Start TeamViewer**.
3. Once TeamViewer starts, the TeamViewer ID and passcode display. Provide both of these to Illumina Support.
4. At the conclusion of the session, select **Stop TeamViewer** to close the connection.
1. If **Stop TeamViewer** is not selected within the Control Software, the TeamViewer connection **automatically** closes after 3 days.

*Enabling TeamViewer in the Illumina Tech Support Console*
If the Control Software is not accessible or cannot initialize, use the following steps to access TeamViewer using the Illumina Tech Support Console.
1. If the Control Software is presenting a Critical Error message that is preventing initialization, select **Minimize**.
2. Double-click to **Illumina Tech Support** console icon in the top left corner.
3. Input **1** and then press **Enter**.
4. Once TeamViewer has started, the **Session ID** and **one-time passcode (OTP)** will populate. Provide both of these to Illumina Support.
