# How to disable and add exceptions to the Software Restriction Policies for TeamViewer in Windows 10
**Background**
Instruments with Windows 10 Operating System (OS) have the Software Restriction Policies (SRP) feature enabled by default. This security feature blocks programs that are not specifically on the SRP exceptions list. When using TeamViewer QuickSupport (QS), an exception must be added to SRP to allow TeamViewer QS to launch properly.
**Resolution Actions**
*Disabling and Enabling SRP*
1. Confirm that a sequencing run is not in progress and the instrument is idle.
2. Log in to the Windows OS using the `sbsadmin` local Administrator account.
1. For NovaSeq 6000 with serial numbers smaller than A01535, the `sbsuser` account is part of the Administrators group.
3. Open Windows **File Explorer** and navigate to the `C:\Illumina\Security` folder (Figure 1).
4. Double-click **Disable.reg** and acknowledge the prompts (Figures 2, 3).
5. When finished, double-click **Enable.reg** and acknowledge the prompts to re-enable SRP.
*Adding Exceptions for TeamViewer to SRP*
1. Confirm that a sequencing run is not in progress and the instrument is idle.
2. Log in to the **Windows OS** using the `sbsadmin` local Administrator account.
1. For NovaSeq 6000 with serial numbers smaller than A01535, the `sbsuser` account is part of the Administrators group.
3. Disable SRP by navigating to `C:\Illumina\Security`, double-clicking **Disable.reg**, then acknowledge the prompts (Figures 1-3).
4. In the Windows search bar, input `secpol` and open the Local Security Policy App (Figure 4).
5. In the **Local Security Policy** dialog box, expand **Software Restriction Policies**, then select **Additional Rules** (Figure 5).
6. To add a rule:
1. On the **Action** menu, select **New Path Rule**….
2. In the **Path** field, enter the certificate, file name, file extension, or directory that you want to allow.
3. In the **Security level** list, select **Unrestricted**.
4. \[Optional] In the **Description** field, enter a reason for creating the rule.
5. Select **OK** to add the rule.
7. Separately add the following rules using **Steps 6a-e** for both of the following paths (Figures 6, 7):
1. `TeamViewerQS*.exe`
2. `C:\Users\*\AppData\Local\Temp\TeamViewer\*`
8. Close the **Local Security Policy** application.
9. Reenable SRP by navigating to `C:\Illumina\Security`, double-click **Enable.reg**, then acknowledge the prompts.
10. Sign out of `sbsadmin` account and then sign back in as `sbsuser` for the settings to take effect.
**Figure 1:** Double-click **Disable.reg** to disable SRP.
**Figure 2**: Select **Yes** to acknowledge the prompt.
**Figure 3**: Select **OK** to acknowledge the prompt.
**Figure 4**: Open **Local Security Policy** to add exceptions for TeamViewer to SRP.
**Figure 5**: Expand **Software Restriction Policies** and then select **Additional Rules**.
**Figure 6**: Select **Action** and then select **New Path Rule**...
**Figure 7**: Input `TeamViewerQS.exe` in the **Path** free-text field and select **Unrestricted** in the Security Level drop-down menu, then select **OK**. Repeat these steps to add `C:\Users\*\AppData\Local\Temp\TeamViewer\*` as a second Path Rule.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://knowledge.illumina.com/instrumentation/general/instrumentation-general-reference_material-list/000006523.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
