All: This issue is on VMware's radar and is currently being investigated.
In the meantime, here's a possible workaround. Note that this disables support for Horizon Smart Policies (which were introduced in Horizon 7 and UEM 9.0).
- Stop the UEM service
- Create a HorizonLogic REG_DWORD registry value at HKLM\SOFTWARE\Immidio\Flex Profiles (if you're using Group Policy to configure UEM), or at HKLM\SOFTWARE\VMware, Inc.\VMware UEM\Agent\Configuration (if you're using NoAD) and set it to 0
- Start the UEM service
- Remove the Version registry value at HKLM\SOFTWARE\VMware, Inc.\VMware UEM if present
Again, this will break Horizon Smart Policies. UEM will still put the relevant smart policies configuration settings into the registry, but the corresponding Horizon components might no longer pick up that configuration.
