Message "OS not compatible" when installing Safetica on endpoints
Posted by Ladislav Mlčák, Last modified by Štěpán Horký on 12 June 2019 03:13 PM

When installing Safetica to endpoints via Update and Deploy screen or via Endpoint Management screen, you may encounter the message "OS not compatible". The station will have Safetica Agent installed, but not Safetica Client. In case you were updating Safetica on the station, the Safetica Client will remain in the old version.

This message is shown when the station does not support DualSign driver certificates, or has SecureBoot enabled in their UEFI (BIOS). This situation can be solved by installing missing Windows updates on the stations. The requirements for installing Safetica are:

  • Windows XP 64bit 
    Install Service Pack 2 and all available Windows updates
  • Windows 2003 R2 64bit
    Install Service Pack 2 and all available Windows updates
  • Windows 7 64bit
    Install KB3033929 on the station(s)
  • Windows 2008 R2 Server 64bit
    Install KB3033929 on the server(s)
  • Windows 10
    Disable SecureBoot in your UEFI (BIOS) configuration as described e.g. here:

Windows Vista x64 and Windows 2008 Server (without R2) are not supported due to missing support for DualSign certificates. All other Windows versions support DualSign certificates and do not require specific Windows Update.
