How to fix: "Do you want to allow this app to make changes to your device?"
This guide is provided by Conductor, the service that powers the QuickBooks Desktop integration for many business tools, including the one that sent you here.
If you ever see the Windows prompt shown below whenever you attempt to sync with QuickBooks Desktop, it is preventing the Web Connector from syncing with QuickBooks Desktop. To resolve this issue, you need to adjust your Windows User Account Control (UAC) settings to prevent this prompt from appearing. Please follow the steps in this guide to resolve this issue.
Solution
Open User Account Control Settings
Click on the Windows Start button and type “UAC” in the search box. Select “Change User Account Control settings” from the search results.
Adjust the UAC level
A window will appear with a slider that controls the UAC notification level. Drag the slider all the way down to “Never notify”.
Confirm the changes
Click “OK” to save the changes. You may be prompted to confirm this action - click “Yes” to proceed.
Restart your computer
Restart your computer to ensure the changes take effect.
After completing these steps, Windows will no longer display UAC prompts when applications attempt to make changes to your device. This will prevent the prompt from interfering with the QuickBooks Desktop synchronization process.
