How to test if the hardware key is okay or if the parallel port is ok?
A-6. To test the port, please print to a printer connected from it. To test the key, you may have to load the key and CAEPIPE on another machine. Execute CAEPIPE. If you get an error that says, “Protection error, key not found”, then that key may be defective. Alternately, try the Hardware key finder utility available on our website (under Support > Utilities).
