In the Full Infrastructure model and using the App-V v5 Console UI interface, package path is specified when the package is added. To update the package path, delete the package and then add the package again specifying the correct path.
In the Full Infrastructure model and using the App-V v5 Powershell CmdLets, the package path is specified when the package is imported (Import-AppvServerPackage). To update the package path using Powershell, remove the package (Remove-AppvServerPackage) and then import the package (Import-AppvServerPackage) specifying the correct path.
In the Full Infrastructure model, App-V v5 clients receive the updated package path from the publishing server at the next refresh (or Sync-AppvPublishingServer).
On a standalone App-V v5 client using App-V v5 Powershell CmdLets, the package path can be changed using the Set-AppvClientPackage with the -Path switch. It is also specified via Add-AppvClientPackage.
