Opening Application Installs New Application
You assign or publish an application with a Group Policy object, and a user installs the managed application. When the user opens the application, a new application installs. For example, opening Microsoft Word starts Microsoft FrontPage installation.
Possible Causes:
You set Auto-Install when configuring the application in the Software Installation snap-in.
You created an upgrade relationship between the existing (base) application and the new (upgrading) application.
The Download missing CLSID from Active Directory Group Policy is enabled.
The application that starts shares a class identifier (CLSID) with the published application.
Diagnostic Tests:
Check the file name extension priorities for the Group Policy object.
Check for an upgrade relationship to the base application.
Start the Group Policy snap-in and check for the Download missing CLSID from Active Directory Group Policy.
Check the CLSIDs for the two applications for duplicate CLSIDs.
Note
Checking Event Viewer for the application log does not provide any useful information for this problem because the new application installs correctly. It is not an installation error; rather, it is a case of correctly installing the wrong application.
