I have created several golden apps using the run path and source of

But when using ZFS to distribute these apps the MSI's keep failing.
All the apps pointing at a setup.exe are fine its only the msi's that
are failing with the following error:

Failed to process package. Details: Failed to copy the files in
component: App0. Reason: The variable NULL is undefined

I have tried adding a variable to the subscriber of %zenapps_server%
and the server name but it doesnt appear to have made much difference.
Any ideas??
