You create a Microsoft Application Virtualization (App-V) application.
You deploy the source for the application to a System Center 2012 Configuration Manager distribution point.
You change the application by using the App-V Sequencer.
You deploy the content for the updated application to the distribution point.
In this scenario, when users run the application, your changes are not included in the application.
This problem occurs because the App-V Sequencer saves the virtual application's SFT file (.sft) using a different name when changes are saved for the application. For example, if your virtual application is named MyApp.sft, the App-V Sequencer will save the changed application as MyApp_2.sft. Without manual adjustment, the Deployment Type for the App-V application will still refer to the original .sft file name.
To work around this problem, change the Deployment Type to refer to the current .sft file manually.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
Because the file name changes when you update an App-V application, Binary Delta Replication is not used to download the updated content to the clients. Binary Delta Replication is possible only when you work with two versions of a file that have the same name.
