From the Application Virtualization Server Management Console, for a package that has multiple versions, you can use the following procedure to delete one or more versions and still stream the remaining versions of the package. You might do this to more effectively manage files on the server or to remove an obsolete version.
When you choose to delete a version, a confirmation box reminds you that client computers might still be using it. You should advise users to exit and unload any applications before you remove a version that is in use.
To delete a package version
In the left panel of the Application Virtualization Server Management Console, expand Packages.
Click the package that contains the version you want to delete.
In the center pane, right-click the version of the package you want to delete and choose Delete.
Read the confirmation window, and click Yes to complete the action.
If you have users in disconnected operation, their applications will be replaced with the new versions the next time they connect to the servers. After you are sure all users have updated applications, you can delete old versions.
