When trying to run IRRICAD Link for AutoCAD but it appears to hang at "Loading plug-ins C:\\Program Files\\Irricad\\Irricad Link AutoCad\\irricad64.arx\" and doesn't get past the AutoCAD splashscreen the likely cause is the dongle.
1. Check that the dongle is securely inserted into the USB port or try another port.
2. In some cases it appears that the presence of a USB 3.0 device can interfere with the IRRICAD dongle. Unplug any USB 3.0 device and try running IRRICAD again.
Note, If IRRICAD has just been installed check that the "Sentinel Protection Installer" is listed in the Control Panel | Programs and Features. If it is, restart the computer. If it is not, then download and install the driver from https://www.irricad.com/irricad/downloa ... r7.6.9.exe.
