Error message when installing drivers?

[nachoh44325434]

I have gotten this same "System extension cannot be used" error message, and I think it is connected to my inability to select double-sided printing from the print menu.  How do I reinstall this file?

Hi nachoh44325434,

Please re-install your Printer drivers. If you are experiencing any issue with it please consult your Printer manufacturer support team, they will help you to get it fixed.

I already did that.

So, what did the Printer Manufacturer support team have to say about this?

It's not a Canon issue, it's an Adobe issue.  I am able to print double sided in other programs, but the option is greyed out when I try to print PDF's.

Well, if you prefer to see it as an Adobe issue that's fine, but I think talking to the Printer Driver people may be worth a shot. (No, I don't work for Adobe). It's their module that isn't loading.
