I have created several apps using the run path of

But when using ZFS to distribute these apps they 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??
