Q: I have a MacBook Air and bought a Canon MP495 printer scanner with WiFI. Since the Mac gas no disk drive and had to down load the printer, scanner drivers and a navigation and network software from Canon's website. How do I get the software to work?

I have down loaded printer,scanner drivers and 2 applications Navigator and Network from Canon's website. I cannot seem to get these to run althought the printer works when connected to the Mac with a LAN cable Canon's documentation is useless because it relies on downloading a disc which you cannot do without a CD drive that MacBook Air does not have. Any suggestions appreciated.
