Installing Guardant USB keys

A Guardant USB key is a device designed to protect TRASSIR and associated data from unauthorized use and coping. Each TRASSIR license contains the number of a USB key that must be used to start and run the software.

You will not be able to work with TRASSIR if:

  • The USB is not connected to the computer on which TRASSIR is installed;
  • The drivers for the USB key are not installed or there were errors when installing them;
  • The USB key's physical number and the number specified in the TRASSIR license do not match.

To install drivers for Guardant USB keys:

  1. Be sure you have administrator rights. Otherwise, you will not be able to install the drivers.
  2. Download the drivers for the Guardant USB key from the manufacturer's website or the DSSL website. Additionally, drivers for the keys can be found on the TRASSIR CD. When downloading drivers for the USB keys, you must bear in mind your operating system's version and bus width (32-bit or 64-bit).
  3. Disconnect all other keys (if there are any connected). The Guardant USB key should be connected to the port only after installing the drivers. The a key is connected before the drivers are installed and the standard Windows device installation wizard starts up, remove the key from the port and terminate the wizard.
  4. Close all applications to avoid file-sharing errors.
  5. Run GrdDriversRU.msi or Setup.exe and follow the installation program's instructions.
  6. After completing the installation procedure, verify that the Guardant USB key works. To do this:
    • Connect the Guardant USB key.
    • Be sure that the key's network indicator is constantly lit.
    • Be sure that the Guardant USB key is in the Windows device manager's list of hardware.

Tip

You can install drivers for Guardant keys at the same time you install TRASSIR, because the TRASSIR distribution includes the required drivers.
