ERA upgrade problem

[rafipl 0]

Hello, I am trying to upgrade ERA and Endpoint Security. I tried without uninstalling products - no luck. I uninstalled all and tried install Agent, but no luck. Log:

Property(C): P_LOAD_APPDATA_DIR_STATUS = ERROR_UUID_NOT_READ_FROM_DB
=== Logging stopped: 2019-01-15  11:45:46 ===
MSI (c) (00:04) [11:45:46:400]: Note: 1: 1708 
MSI (c) (00:04) [11:45:46:400]: Product: ESET Remote Administrator Agent -- Installation failed.

Tried with Unninstaller Tool in Safe Mode but there is still problem. I was trying to install it local with prepared cmd file. When I Try to install directly from MSI there I become error: "the database cannot be upgraded"

Hi,

• what installer did you use, ERA 6.5? or upgrade task?
• What version of ERA/ESMC do you have?
• Did you tray manuall uninstallation of the ERA Agent? https://support.eset.com/kb6007/
