After installing Firefox and Adobe Reader on the master target device and updating the vDisk, users report the new applications are NOT visible. What should a Citrix Administrator do to resolve this…

Citrix Provisioning Services uses a vDisk versioning model where updated versions start in 'Maintenance' or 'Test' mode, which limits access to designated maintenance or test devices only. End-user target devices are only allowed to stream a vDisk version that is explicitly in 'Production' mode. Promoting the updated vDisk version to 'Production' causes standard user devices to boot from the new version, making Firefox and Adobe Reader visible to all users.

Merging vDisks consolidates multiple versions into a single base image but does not change the access mode, so end users still could not stream the updated version.

Reverting to the previous vDisk version would remove the newly installed Firefox and Adobe Reader, which is the opposite of the intended result.

'Update Machines' on a Machine Catalog is an MCS operation for pushing image updates and is unrelated to PVS vDisk version mode management.
