There shouldn't be anything special you need to do for this. If the apps (Windows apps or anything else you install in the base image) are on the IC base image, they should work when AppStacks/Packages are attached, unless the Package specifically includes programs that overwrite what's on the base image.
Which version of App Volumes are you running?
How are you creating your App Volumes packaging machine?
- A common practice is to use a clone of your IC base image with the Horizon agent removed as your packaging machine. This helps to ensure there is no configuration drift between the packaging machine and the VMs that will attach the Packages.
- Be sure to take a snapshot of the VM before you ever use the VM for packaging, and be sure to revert to snapshot between each use.
