Reasons
You mostly face this error while installing QuickBooks or downloading its recent updates. The following 
PC conditions might obstruct the bookkeeping software installation-
• An incorrect User Account Control (UAC) settings setup can stop the QBDT installation on your 
system.
• Damaged installation package due to unstable network connection.
• Windows Installer fails to access or process the installation package if the .NET framework or 
MSXML are damaged.
Solutions
QBDT installation won’t start, or the process will instantly terminate in between after this error strikes 
your PC. The methods you can use to prevent issues during QBDT installation are given below-
Solution 1- Ensure the UAC settings are correctly configured in your Windows
This error can arise when the Windows installer fails to run the installation package. This can happen if the 
Microsoft Components are damaged or the installer faces restrictions. User Account Control settings play a 
major role in preventing your system configuration from getting changed by unwanted or harmful 
applications. If these settings are set strictly, they can forbid you from installing or updating applications on 
your PC. QuickBooks installation can also suffer a direct impact due to this, so you must ensure the UAC 
settings are configured correctly as the following steps define-
• Open the control panel on your system and approach the Accounts option.
• Tap User Accounts in the next window and click Change User Account Control Settings.
• The next window contains a slider that acts as a controller for configuring the UAC settings.
• Move the slider beside Never Notify to turn off the settings and try installing QuickBooks.
• After complete installation, put the slider beside Always Notify to turn the settings on again.
If the error persists, it can be due to damaged Windows Components (.NET framework & MSXML). You must 
take professional help to fix the components as it requires IT knowledge. Try the next solution to fix the 
installation issues automatically.
Solution 2- Launch QuickBooks Install Diagnostic Tool to mend QBDT
QB tool hub is a convenient option for dealing with minor issues hindering the software’s installation 
process. You must download the latest version (1.6.0.3) of the tool hub on your PC and use the following 
steps to fix the problem-
