How to Fix QuickBooks Error 15103

Fixing QuickBooks Error 15103 may involve multiple steps, depending on what caused the error in the first place. Below are several troubleshooting methods to help you resolve the issue.

Solution 1: Check and Verify the Digital Signature Certificate

QuickBooks requires a valid Digital Signature Certificate for verifying updates. If this certificate is missing or invalid, it can lead to update issues like Error 15103.

2. In the folder, locate the file named QBW32.exe.

4. Click on the Digital Signatures tab and ensure that Intuit Inc. is listed as the signer.

1. Restart your computer in Safe Mode by pressing F8 while your computer is starting up.

2. Once in Safe Mode, open QuickBooks Desktop.

3. Try to update QuickBooks or Payroll again.

4. After completing the update, restart your computer in normal mode and check if the error is resolved.

1. Open Internet Explorer and click on the Tools icon in the top-right corner.

2. Go to Internet Options and select the Security tab.

6. Click on LAN Settings and ensure that the Automatically detect settings option is checked.

7. Click OK to save your changes.

Solution 4: Disable Antivirus and Firewall Temporarily

Your firewall or antivirus software may be blocking QuickBooks from connecting to the internet, which can prevent it from downloading payroll updates.

1. Open your antivirus or firewall software.

2. Temporarily disable the protection features.

3. Try updating QuickBooks again.

4. Once the update is complete, enable your antivirus or firewall software to ensure your system remains protected.

Note: If disabling your firewall allows the update to complete, consider adding QuickBooks as an exception in your firewall settings.

Solution 5: Run QuickBooks as Administrator

Running QuickBooks with administrator privileges ensures that the software has the necessary permissions to update successfully.

1. Right-click on the QuickBooks Desktop icon.

2. Select Run as Administrator from the context menu.

3. Try updating QuickBooks again.

4. After completing the update, check if the error is resolved.
