How to revert extension points from an App-V 5.1 package to an App-V 4.6 package for all users on a specific computer
Use the following procedure to revert extension points from an App-V 5.1 package to the App-V 4.6 file format using the deployment configuration file.
To revert a package
Ensure that App-V 4.6 package is published to the users but the FTAs and shortcuts have been assumed by App-V 5.1 package using the following migration method, How to Migrate Extension Points From an App-V 4.6 Package to a Converted App-V 5.1 Package for All Users on a Specific Computer.
In the userConfiguration section of the deployment configuration file for the converted package, to set the policy, make the following update to the userConfiguration section: ManagingAuthority TakeoverExtensionPointsFrom46="false" PackageName=<Package ID>
From an elevated command prompt, type:
PS>Set-AppvClientPackage $pkg -DynamicDeploymentConfiguration <path to deployment configuration file>
PS>Publish-AppVClientPackage $pkg -DynamicUserConfigurationType useDeploymentConfiguration
Perform a publishing refresh, or wait for the next scheduled publishing refresh for the App-V 4.6 package.
Open the application using FTAs or shortcuts. The Application should now open using App-V 4.6.
Note
If you don't need the App-V 5.1 package anymore, you can unpublish the App-V 5.1 package and the extension points will automatically revert to App-V 4.6.
