  Desktop integration for many business tools, including the one that sent you

If you were directed to this page, it was likely because you encountered the following error attempting to sync with your QuickBooks Desktop:

```
We could not connect to your QuickBooks Desktop because there is a configuration issue with your QuickBooks Desktop.
```

This error means QuickBooks Desktop could not be opened for this connection. Common causes include a stale saved company-file path, multiple QuickBooks Desktop versions, permission mismatches, or other local QuickBooks Desktop configuration issues. Please follow the steps below to resolve the issue.

<Steps>
  <Step title="Ensure only one version of QuickBooks Desktop is installed">
    Only one version of QuickBooks Desktop can be installed on your Windows computer for this integration to work. **If the Web Connector crashes when syncing, this is almost certainly the culprit.** Please [complete this guide](/help/guides/ensure-only-one-version-installed) to ensure only one version of QuickBooks Desktop is installed on your computer.

    After completing the guide linked above, try syncing with QuickBooks Desktop again.
  </Step>

  <Step title="Recreate the Web Connector log file">
    If you continue to see the same error when syncing, you may need to recreate the Web Connector log file. Please [complete this guide to delete the log file](/help/connection-errors/there-was-a-problem-with-the-log-file#solution%3A-delete-the-web-connector-log-file). If you recognize the error pop-up below, then this is certainly the culprit. Even if not, it's a good idea to delete the log file (as described in the guide) to ensure it's not corrupted.

    After deleting the log file as described in the guide, try syncing with QuickBooks Desktop again.
  </Step>

  <Step title="Ensure QuickBooks Desktop and the Web Connector are not set to 'Run as administrator'">
    For the integration to work, **QuickBooks Desktop and the QuickBooks Web Connector must launch with the exact same Windows permission level**. If one is set to "Run as administrator" while the other is not, the Web Connector will be unable to connect to QuickBooks Desktop. Please [complete this short guide](/help/guides/run-as-administrator-disabled) to ensure "Run as administrator" is disabled for both programs.

    After completing the guide above, try syncing with QuickBooks Desktop again.
  </Step>

  <Step title="Remove and re-add the Web Connector connection">
    Reinstalling the connection resets QuickBooks's integration permissions, resolves many lingering connection issues, and often fixes problems that appear right after a QuickBooks Desktop update.

    1. Open QuickBooks Desktop with the correct company file, sign in as the built-in **Admin** user, and switch to single-user mode.
    2. In the top menu bar, click "**File**" → "**App Management**" → "**Update Web Services**" to launch the QuickBooks Web Connector.
    3. In the Web Connector window, click "**Remove**" to the right of the connection and then click "**Yes**" to confirm.
    4. **Return to the QuickBooks Desktop integration setup flow** you used to create this connection. If you do not know how to access it, contact the support team for the product that sent you this guide.
    5. Download a fresh configuration file from that setup guide. In the Web Connector, click "**Add an Application**" and select the file you just downloaded.
    6. Finish the setup flow until the final page confirms the connection is successful, and then try syncing again.

    <Info>
      QuickBooks Desktop may skip the permissions prompt this time. That is normal and does not indicate a problem.

  </Step>

  <Step title="Did you recently move the connection from one computer to a new computer?">
    If you recently moved the Web Connector connection from one computer to a new computer, double-check that the connection on the old computer is disabled. Having connections active on both computers can cause synchronization conflicts and lead to connection errors. Please [follow this guide to properly move your connection](/help/guides/move-computers) and **ensure the old connection is disabled**.

    After completing the guide above, try syncing with QuickBooks Desktop again.
  </Step>

  <Step title="Did you recently move or rename your QuickBooks company file?">
    If so, [follow this guide](/help/guides/moved-or-renamed-company-file) to reset the saved company file location (on our server) for this connection.

    After completing the guide above, try syncing with QuickBooks Desktop again.
  </Step>

  <Step title="Do you see a popup on your Windows computer saying 'Do you want to allow this app to make changes to your device?'?">
    If you still see the same error when syncing, check if the dialog box shown below appears on your Windows computer. If so, please [complete this guide to resolve that issue](/help/connection-errors/do-you-want-to-allow-this-app-to-make-changes-to-your-device). Then, try syncing with QuickBooks Desktop again.

    <Image src="/images/help/connection-errors/do-you-want-to-allow-this-app-to-make-changes-to-your-device/do-you-want-to-allow-this-app-to-make-changes-to-your-device.jpg" alt="QuickBooks Desktop - Do you want to allow this app to make changes to your device" width={400} />
