During the MassCore - Interval Zero RTX64 installation through MT Security panel, the installer rolls back and fails.
Your MassCore / RTX64 license is hosted on a dedicated dongle (SSK-HUD-RTX)


There is a compatibility issue between the dedicated MassCore / RTX64 license dongle (SSK-HUD-RTX) and the CEDAR license dongle.

  1. Go in Windows Control Panel > Programs & Features and uninstall "Sentinel Runtime" (you may sort the programs by Installation date, to see which one was installed at the same time as "CEDAR for Pyramix64").
  2. Go in Windows Control Panel > Device Manager > Universal Serial Bus controllers.
    Right click on "Sentinel HASP key" and select Uninstall
    Tick the box "Delete the driver software for this device"
  3. Repeat the same operation for the "Sentinel HL key"
  4. Reboot your computer.
  5. Go in MT Security panel > MassCore tab and reinstall MassCore

After the MassCore installation, the CEDAR license dongle will work as well.
