Purchased an MX922 Canon All-In-One - I received errors upon installing and after a lengthy support session with Canon Support, no solution could be found. After continuing to search around I came about the following post which fixed the problem. Below is the original solution I found, however, I only had to remove Avast (not reinstall and remove again) and it did finally allow the Canon drivers to load correctly and install the Quick Menu, which Avast was unknowingly blocking. Avast Support and Canon Support need to work this out - it was a very time consuming and lengthy process to finally figure out Avast was the problem. Avast & Canon Support - TAKE NOTE!

Don’t know if this will help but I found a solution for it not installing on my systems.
Fresh install of win 8.1 pro and it installs fine
add avast anti virus and it works but if you try to install it fails
turn off all features of Avast and it still fails to install
uninstall Avast and reboot and it will still fail to install
found out Avast does not uninstall and blocks the network scanner selector program from setting the connection
Solution albeit strange and can’t confirm if it works for other anti virus software is:
uninstall Avast
install Avast again
uninstall Avast right after the fresh install
Appears to be the only way to get Avast to completely uninstall
Load all your Canon drivers and test
If all work and they probably will
Install Avast
Again, this may be similar issue with other anti virus software but can’t confirm
Had to do this proceedure on a laptop, a tablet, and 3 desktops and it has worked on all of them
good luck and hope it helps
