Understanding Error 15215

When QuickBooks Error 15215 occurs, the error message “Unable to verify digital signature” is usually displayed.

It guarantees that no corruption or tampering occurs with the file while it is being transmitted.

Causes of QuickBooks Error 15215

  • Interference from another application: This error most commonly arises when another application conflicts with QuickBooks’ operations. This can include antivirus programs, firewall settings, or other background processes.
  • Incorrect configuration of Internet Explorer: Since QuickBooks uses Internet Explorer’s settings to connect to the Internet, incorrect settings can lead to connection issues.
  • Outdated software: Not running the latest version of QuickBooks can also lead to compatibility issues and errors.

Steps to Fix QuickBooks Error 15215

  • Open Internet Explorer.
  • Click on the Gear icon, then select “Internet Options.”
  • Go to the “Advanced” tab.
  • Scroll down to the “Security” section and check if “Use TLS 1.0” is checked and if “Use TLS 1.1” and “Use TLS 1.2” are unchecked.
  • Click “Apply” and then “OK.”
  • Restart your computer and try to update again.

Eliminate Conflicts with Other Applications

Other applications, particularly antivirus and firewall settings, can interfere with QuickBooks updates. Temporarily turn off these programs to check if they are causing the issue.

  • Right-click on the antivirus icon in the system tray.
  • Select “Disable” or a similar option.
  • Specify the duration for which you want the antivirus to remain disabled.
  • Try updating QuickBooks again.

Note: Be sure to re-enable your antivirus software after testing to keep your system protected.

Restart Windows in Selective Startup

Performing a selective startup (or clean boot) can help identify if background applications are the cause of the error.

  • Press Win + R to open the Run window.
  • Type msconfig and press Enter.
  • In the System Configuration Utility, select “Selective Startup.”
  • Uncheck “Load Startup Items.”
  • Click “Apply,” then “OK,” and restart your computer.
  • Once restarted, try updating QuickBooks again.

Reinstall QuickBooks
