I have posted this question to Canon technical support. They have not been able to solve it. I have run their software in the newest iMac 27 and the newest Macbook Air unsuccessfully.
I think that their software does not recognise my the computer, so no communication between the driver and the computer. The problem has been about 10 months.
I see this:
Version CaptureOnTouch P-150M 1.2.11.0722, Canon Electronics Inc.
How can you install CaptureOnTouch in OSX Mountain Lion?
