Failed to apply changes to software installation settings. %1 The error was : %%%2

Product: Windows Operating System
Event ID: 108
Source: Application Management
Version: 5.2
Message: Failed to apply changes to software installation settings. %1 The error was : %%%2

An application could not be installed or uninstalled.

The cause of the failure depends on the type of operation that failed: an uninstall, install, reinstall, or the domain controller query to determine administrative policy. The events indicate that software was assigned in addition to being installed. Assignment is simply the first phase of an installation. For troubleshooting purposes, treat assignment failures in the same manner as installation failures.

Possible causes include:


  • The Group Policy Software Installation extension might need to uninstall software.
  • The system is using a file that needs to be accessible when the application is uninstalled.
  • The Windows Installer package that was used to deploy the application was authored incorrectly.

Install or reinstall.

  • The installation source for the software is not available.
  • The application is already installed on the computer but has a different set of transforms from the application deployed through Group Policy.
  • An existing application on the computer conflicts with the application and is preventing it from being installed.
  • The Windows Installer package of the deployed application is incorrectly authored.


  • The Group Policy Software Installation extension attempted to upgrade an application, but was unable to do so due to an installation or uninstallation error; the event logs provide additional information.

Domain Controller query failed.

  • The Group Policy Software Installation extension could not access the network, and was not able to query a domain controller for the user or computer.
User Action

To troubleshoot this problem, try one or all of the following:

  • Determine whether any other
    related events are logged in Event Viewer. Windows Installer usually logs a related event that provides
    details about why the operation could not be completed.
  • Check for errors in any application
    deployed to the computer.
  • Enable logging for Application Management and Windows Installer.
  • Log on to another computer as an administrator, verify that the application can be manually installed
    and uninstalled on that computer. If this verification fails, the problem is probably a software issue.
    Contact the software support provider.
  • In the case of an install or uninstall failure, manually
    uninstall the software.
  • If the event indicated that the transforms of the deployed application
    are different from the transforms of an instance of the same application already installed on the computer,
    deploy a new version of the application that has the same set of transforms as the existing installation,
    and then remove the deployment that has the conflict. Deployment changes can be made by a network
    administrator with the right to manage Group Policy Objects (GPOs) in the Windows domain of the user or
  • If the problem is the Group Policy Software Installation extension failing to access
    network information related to software installation policy, run the Ping, DCdiag.exe, and the Nslookup
    tools on the computer that is having the problem. This helps determine where on the network the problem
    is occurring.

You can use Group Policy to enable logging for Windows Installer by using the
Logging policy setting in the Computer Configuration\Administrative Templates\Windows Components\Windows
Installer node of Group Policy Object Editor.

To learn more about the tools that you can use to
force an application uninstall, see the Windows Installer documentation.
