QuickBooks is a powerful accounting tool, but like any software, it can encounter issues related to updates. One such common update error is QuickBooks Error 15224, which typically appears when users try to update QuickBooks Desktop or download the latest payroll updates. This error is often connected to incorrect internet settings, SSL configuration issues, or disrupted QuickBooks services. If you’re stuck due to this error, here’s a complete guide to help you understand and resolve it quickly.
QuickBooks Error 15224 generally pops up when the QuickBooks update process is unable to verify the digital signature of files. Since updates must be authenticated for security reasons, any mismatch or failure in verification stops the process and triggers this error. It mainly affects QuickBooks Desktop updates, payroll tax table updates, and other connected services.
Here are the most common reasons behind this issue:
Incorrect or outdated internet settings.
Internet Explorer plays a crucial role in QuickBooks’ connectivity, and misconfigured settings can cause update failures.
SSL certificate issues.
If the SSL settings are wrong or corrupted, QuickBooks cannot establish secure communication with Intuit servers.
Firewall or antivirus interference.
Security programs may mistakenly block QuickBooks update services.
Unverified QuickBooks digital signature.
QuickBooks uses digital signatures to authenticate update packages. If these aren’t validated, updates fail.
Corrupt QuickBooks installation files.
You may notice:
Sudden crash while updating QuickBooks
Slow performance during updates
Error message: “Error 15224: The QuickBooks update cannot proceed”
Failed payroll or software update downloads
Follow these step-by-step solutions:
QuickBooks relies heavily on Internet Explorer for network communication.
Open Internet Options
Go to Advanced tab
Ensure SSL 2.0 and SSL 3.0 are enabled
Check TLS 1.2 and uncheck outdated versions if needed
Set IE as the default browser
Restart and try updating again.
Navigate to C:\Program Files\Intuit\QuickBooks
Right-click QBW32.exe → Properties
Open Digital Signatures tab
Select Intuit Inc. → Click Details
Click View Certificate → Install Certificate
Restart QuickBooks and retry the update.
Allow QuickBooks components through your security software:
QBW32.exe
QBUpdate.exe
Intuit servers (service URLs)
Restart your PC afterward.
Open QuickBooks Desktop
Go to Help > Update QuickBooks Desktop
Select Reset Updates
Click Get Updates
Use the QuickBooks Tool Hub → Clean Install Tool to repair corrupted installation files.
Incorrect internet or SSL settings, digital signature issues, or blocked update services primarily trigger QuickBooks Error 15224. By following the above troubleshooting steps, you can easily fix the update-related problem and get QuickBooks running smoothly again. Regularly updating your software and maintaining proper system settings prevents this error from resurfacing.
