Fixing QuickBooks Error Code 15106: Server Error During Update

QuickBooks is one of the most trusted accounting software solutions for small and medium-sized businesses. But like any software, it’s not immune to errors. One common issue users face is QuickBooks Error Code 15106, often accompanied by a message like “The update program cannot be opened” or “Server error during update.” If you're seeing this, don’t panic—we’ve got the fix!

Error 15106 usually pops up when you're trying to update QuickBooks Desktop or its payroll service. It’s considered a part of the 15100 series errors, which are generally related to update issues. The error indicates that something—usually a security program or permission setting—is blocking the update process.

Here are the typical reasons why this error might appear:

• Antivirus or security software interference (e.g., Webroot, Norton)

• Insufficient admin privileges

• Corrupted QuickBooks update files

• Incorrect UAC (User Account Control) settings

• Damaged Windows user profile

Right-click on the QuickBooks icon on your desktop and select "Run as administrator." This gives QuickBooks the necessary permissions to complete updates.

Your antivirus or security software may block the update process. Try temporarily disabling it:

• Go to the antivirus settings

• Turn off real-time protection

• Retry the QuickBooks update

⚠️ Remember to enable your antivirus again after the update.

This step can clear any corrupted update files:

• Go to: C:\Program Files\Intuit\QuickBooks [version]\Components

• Find the folder named DownloadQBXX (XX = your version)

• Rename it to DownloadQBXX.old

• Reopen QuickBooks and attempt the update again

Sometimes, UAC settings interfere with updates:

• Open the Control Panel

• Search for “UAC” and select Change User Account Control settings

• Slide the bar down to “Never notify”

• Click OK and restart your computer

• Try updating QuickBooks again

If none of the above works, use the QuickBooks Clean Install Tool to uninstall and reinstall QuickBooks completely without affecting your data.
