If you have installed IRRICAD onto a new computer and it gives the "Hardware Key Not Found" message restart your computer to complete the sentinel driver installation.
If this does not solve the issue download the sentinel driver from http://www.irricad.com/Irricad/Download ... r7.6.9.exe and re-install the driver. After a restart IRRICAD should now run.
If you have an issue running the Sentinel Protection Installer see the post http://www.irricad.com/phpbb3/viewtopic ... 579&p=1336
If IRRICAD does not run please contact your local distributor.
