Reasons
You’ll run into this error code while installing QuickBooks or its updates on your PC. The reasons you 
get this error and the installation/update fails are mentioned underneath-
• Your system’s UAC settings aren’t properly configured, leading to a failure in installing or updating 
the software.
• Windows Components, including MSXML or .NET framework, are damaged and cannot run the QB 
installation on your PC.
• QuickBooks fails to install due to the damaged installation package downloaded on your system.
Solutions
After receiving this error message, you won’t be able to install or update your QuickBooks. The usable 
methods to prevent this or any other installation error are mentioned below-
Solution 1- Set up the UAC settings correctly on your system
User Account Control or the UAC settings are employed by Windows to prevent your system configuration 
from getting changed by any new application. As this can be harmful to your system, the UAC settings can 
block the installation or update of applications on your system. QuickBooks can also face trouble installing 
due to these settings on your PC. You can fix the issue by temporarily turning off the UAC settings until 
QBDT is installed on your system. You won’t be able to extract the QB installation package if the settings 
are strictly set. Refer to these steps-
• Launch the control panel on your PC using File Explorer (Windows+E) or the search bar.
• Click the Accounts option in the menu and select User Accounts in the next window.
• Tap the Change User Account Control settings option.
• There’s a slider in the next window, which is used to arrange the UAC settings. Hold your click on the 
slider and drag it to Never Notify to turn off the UAC settings.
• Install QuickBooks again when the UAC settings are off. Move the slider to Always Notify after QBDT is 
completely installed to turn on the settings again.
If the QBDT still fails to install on your PC, move to the next solution.
Solution 2- Remove the issues using QuickBooks Install Diagnostic Tool
You can also run into this installation problem due to minor issues on your PC that can be fixed using 
the QB Tool hub easily. Apply the following steps-
• Run the QuickBooks tool hub on your PC and click the Installation issues option located at the 
top.
• Click Run QuickBooks Install Diagnostic Tool from the options and wait until the tool completes 
the repairs.
• Try installing QBDT again on your system.
