Here are some of the possible causes for errors in "Hardware Protection Device (HPD) not found" errors. Some of the points may seem basic, but all are worth checking.

[*]Check that the dongle works by loading IRRICAD on another machine and using that dongle does IRRICAD run. Hopefully the dongle is not physically broken.

[*]Check that IRRICAD was installed with administrator privileges, as XP requires admin privileges to load the dongle driver. Vista, Windows 7, 8 and 8.1 require Admin privileges and also Write Access to the Temp folder.

[*]Check that the XP firewall is off (can be turned on later).

[*]Check that the dongle is correctly seated in the port.

[*]Check that the Sentinel drivers are loaded correctly by going through "Start/Settings/Control Panel/Add-Remove Programs" and checking that "Sentinel Protection Installer" is present. CANCEL out of this once you have checked it. If the drivers are not present, then you will need to load the drivers from the Irricad CD by going through Explorer ("install/drivers/ etc). Remember when installing IRRICAD or the sentinel driver you should have the USB dongle connected.
If the drivers are present, you could try to download the latest ones from the Safenet website ( ). You will need to uninstall the old drivers first.

[*]Check if the driver is running. Do this through "My computer | Properties | Hardware | Device Manager" then "View | Show hidden devices | Non Plug & Play Devices" you should see the Sentinel.
