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 App-V 5.1 for a Specific User](how-to-migrate-extension-points-from-an-app-v-46-package-to-app-v-51-for-a-specific-user.md). 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>** 2. From an elevated command prompt, type: PS>**Publish-AppVClientPackage $pkg –DynamicUserConfigurationPath** <path to user configuration file> 3. Perform a publishing refresh, or wait for the next scheduled publishing refresh for the App-V 4.6. Open the application using FTAs or shortcuts. The Application should now open using App-V 4.6. **Note** If you do not 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. ~~~ **Got a suggestion for App-V**?
