Signs of QuickBooks Error 15240

You might be dealing with QuickBooks Error 15240 if you notice one or more of these symptoms:

  • Payroll updates fail to download.

  • Error messages mentioning file path or update failure.

  • Crashing or freezing of the QuickBooks desktop application.

  • Slow system performance while attempting updates.

If these issues sound familiar, the following solutions can help you restore QuickBooks functionality.

Top 5 Ways to Resolve QuickBooks Error 15240

1. Verify System Date and Time Settings

QuickBooks requires correct system time and date to establish a secure connection during updates. An incorrect setting may lead to Error 15240.

Steps:

  • Right-click on the system clock on the taskbar.

  • Select Adjust Date/Time.

  • Ensure both the date and time zones are correct.

  • Restart QuickBooks and attempt to update again.

2. Run QuickBooks as Administrator

Sometimes, the software does not have sufficient permissions to run updates, causing QuickBooks Error 15240. Running QuickBooks with administrative rights can solve this.

Steps:

  • Close QuickBooks Desktop.

  • Right-click on the QuickBooks icon.

  • Select Run as Administrator.

  • Try updating QuickBooks or payroll again.

3. Configure Internet Explorer Settings

Since QuickBooks relies on Internet Explorer for connectivity, misconfigured browser settings can also trigger Error 15240.

Steps:

  • Open Internet Explorer.

  • Go to Tools > Internet Options > Advanced tab.

  • Scroll down and ensure both SSL 2.0 and SSL 3.0 are marked.

  • Click OK and exit.

  • Restart your system and retry the update.

4. Check Firewall and Security Settings

Overly strict firewall or antivirus settings might block QuickBooks updates. Make sure QuickBooks has the right permissions.

Steps:

  • Open your firewall/antivirus settings.

  • Add QuickBooks and its update files (QBUpdate.exe and QBW32.exe) to the exception list.

  • Save changes and restart your PC.

  • Run QuickBooks update again.

5. Reinstall QuickBooks Using Selective Startup

If none of the above methods work, the issue could be due to improper installation or interference from background applications. Reinstalling QuickBooks in Selective Startup mode often resolves Error 15240.

Steps:

  • Press Windows + R, type msconfig, and hit Enter.

  • Go to the General tab and choose Selective Startup.

  • Clear the box for Load startup items.

  • Click Apply and restart your system.

  • Uninstall and reinstall QuickBooks Desktop.

  • Switch back to Normal Startup after reinstallation.

Additional Tip: Verify Digital Signature Certificate

Outdated or missing digital signatures can also result in QuickBooks Error 15240. To fix this:

  • Right-click QBW32.exe in the QuickBooks installation folder.

  • Go to Properties > Digital Signatures.

  • Ensure Intuit Inc. is listed.

  • Select it, click Details, then Install Certificate.

Conclusion

QuickBooks Error 15240 can interrupt important payroll updates and disrupt your workflow. By following the methods above—verifying the system time, running as admin, configuring browser settings, adjusting firewall rules, or reinstalling in selective startup—you can fix this error quickly and continue using QuickBooks without interruptions.

However, if you still face issues or feel uncomfortable troubleshooting on your own, reaching out to certified QuickBooks experts at +1-866-408-0444 is the best option. With the right guidance, you’ll have your software updates running smoothly and your accounting operations back on track.
