AppVolumes 2103 (4.4) Tools – Off line packaging for both AppVolumes On-Prem and on Azure

March 26, 2021

One of the great update from AppVolumes 2103 (aka 4.4) is now you can install only App Volumes Tools and package applications offline from a simple VM on VMware Workstation for example and produce the same package for App Volumes on Prem (.vmdk file) and for App Volumes on Azure (.vhd files).
