Description

When publishing an App Layering image with Elastic enabled, M365 may fail to be licensed.  You may find the license is missing at C:\ProgramData\Microsoft\Office\Licenses\5\ 

Environment

Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

Resolution

This is expected to be resolved in ELM 2409

To work around this issue, on the platform layer under HKLM\SYSTEM\CurrentControlSet\Services\Unirsd

Edit ExcludeKey and add the value \Registry\Machine\System\HardwareConfig 

Finalize, update the image template, and republish.
