QuickBooks is a trusted accounting software used by businesses worldwide to handle finances efficiently. While it's packed with features, like any software, it can run into issues from time to time. One common issue that many users face is QuickBooks Error 15106. This error typically occurs when users attempt to update their QuickBooks application. In this article, we'll dive into what QuickBooks Error 15106 is, what causes it, and provide you with a step-by-step guide on how to fix it.
What Exactly Is QuickBooks Error 15106?

QuickBooks Error 15106 appears during the process of updating or installing the software, indicating that there is a problem with the update process. The error is usually related to Windows Installer, a program responsible for managing the installation and uninstallation of software on your computer. If this installer becomes damaged or corrupted, it can lead to various errors, including the one that disrupts QuickBooks updates.
When this error occurs, you’ll likely see a message stating that QuickBooks cannot open the update program, or it may directly mention that the update process is corrupted or unable to continue. In either case, it’s essential to address this issue quickly to ensure that your QuickBooks software is up-to-date and functioning correctly.
Common Causes of QuickBooks Error 15106
There are a variety of reasons why QuickBooks may show the 15106 error when updating or installing updates. Understanding these causes can help you identify the root of the problem and fix it efficiently:
-
Incomplete Installation of QuickBooks
During the installation of QuickBooks, some additional components may not get installed properly, leading to issues when the software tries to update.
-
Interference from Antivirus Programs
Certain antivirus programs, such as Webroot, can block QuickBooks updates. The antivirus may mistakenly identify QuickBooks files as a security threat and prevent the update from proceeding.
-
Problems with Third-Party Anti-Malware Software
If you’re using anti-malware software in addition to your antivirus program, it may also interfere with QuickBooks updates and cause errors like 15106.
-
User Account Control (UAC) Settings
Your computer’s User Account Control settings might prevent QuickBooks from updating. If your user account doesn't have administrative rights, it can cause the error to appear.
-
Microsoft Management Permission Issues
If there are permission conflicts with Microsoft management settings, QuickBooks may fail to update, triggering the 15106 error.
-
Performance Issues
In some cases, the computer may freeze, run slowly, or have an unresponsive mouse after encountering this error. This can further complicate the updating process.
