What Is QuickBooks Error 15104?

QuickBooks Error 15104 generally occurs when the software is unable to verify the digital signature of an update file. As a result, QuickBooks blocks the update process to protect the system from potentially unsafe or unauthorized files.

This error is most commonly encountered during:

What Causes QuickBooks Error 15104?

Several factors can trigger this error. Identifying the root cause helps apply the correct solution.

1. Incorrect User Account Control (UAC) Settings

QuickBooks requires a valid digital signature certificate to authenticate updates. If the certificate is missing, expired, or damaged, Error 15104 may occur.

3. Improper QuickBooks Installation

A damaged or incomplete QuickBooks installation can prevent update files from being accessed or verified.

4. Incorrect Download Location

If QuickBooks is not installed in the default directory, update verification may fail.

5. Third-Party Security Software Interference

Antivirus or firewall programs may block QuickBooks update processes, mistakenly identifying them as threats.

• Frequent update failures
  
  

• Slow system performance during updates
