I am attempting to use dispcal for spyder2pro in Windows7. I first run dispcal -c to have it locate the port, but it comes back with a message ** No ports found ** When I try running dispcal -c 1 or dispcal -c 2, etc., it reports the same message. If I run dispcal -r it reports dispcal: Error - No instrument at port 1 Any hints as to where to go from here? By the way, I installed the spyder2pro2.3.5 drivers, supposedly successfully. Thanks.
