Okay, I'm a moron, but I need to update some drivers and I don't understand what I need to do after I download from the website.

In the 1st case, I need to update the scanner driver for the Canon MP530 which is installed on my US PC.

In the 2nd case, I need to update the drivers and all software for the French version Canon MP530 installed on my US HP Pavillion, which now lives in France.

Can anyone give me a step-by-step? I would really appreciate some help.
