Antivirus 2017 (Bitdefender engine) fails to install.
If Antivirus fails to install on a device it leaves traces behind that will not allow subsequent installs to process properly.
Cleaning up the traces of the failed install will allow subsequent installs to process properly.
Delete the folders and all contents inside:
C:\Program Files (x86)\LANDesk\LDClient\antivirus
C:\Program Files (x86)\LANDesk\LDClient\temp_av
Check the client Services for an existing Landesk(R) Antivirus Service. It also may not exist in certain cases, this can happen and is normal. If it does exist and the install failed it likely isn't running and will fail to start.

Try installing Antivirus 2017 again.
