You stated that you are unable to scan from your PIXMA MX870's Control Panel.
Are you able to initiate the scan from the computer using the MP Navigator EX?

I was able to fix this problem today today after so many months. I did what it says in this video: http://youtu.be/0OUdIZT7C2E
Except that mine was set to "Turn on DEP for all programs"and I changed it to "Turn on DEP for Essential Windows programs"
Now all works fine!!!

My MX870 worked perfectly for a couple of years on the wireless network and all of a sudden this week, I could not scanned with the MP Navigator giving an error message " Cannot start the MP Navigator EX. Check the following points ............"
My laptop runs on Windows 7 Pro. After several days of trying & reloading the drivers & Canon softawares, I discovered the problem might be due to some incompatibility of the MP Navigator with some Windows updates. The problem was completely resolved through the following steps
1. Highlight the MP Navigator icon on the desktop
2. Right click the mouse
3. Select "Properties"
4. Select "Compatibility"
5. Under the "Compatibility mode" choose/tick "Run this program in compatibility mode for"
This works for me and it has been running fine for the last two days

Having a similar problem. I've checked my twain_32 file and all I have in there is the wiatwain.dis file. There are no canon folders. I've got my Canon Pixma M5320 working fine as a wireless printer, but I can't seem to install working scan software. I've installed from the disc, and downloaded software from this site. I get an icon on my desktop, but when I click on it, I get an error message (below).

I just wanted to tell you how I solved the issue. The laptop is fresh Windows 10 installation on a former Windows 7 and 8 upgraded. I tried everything to make it working, including solutions I found on the net and USB connection. My setup is a MG6250 printer conected wifi to a router to which the computer is connected as well in WIFI. I had installed the MP Navigator as administrator and also set the administrator in the properties compatibility setting when running the software, but it wouldn't work.
However, finally the only way it worked was - without uninstalling the software itself as well as the drivers and other related software - to download the MG6200 series Mini Master Setup for Windows 8 64 bit (which was the system on which it worked) and for the MG6250 printer.
This is basically the software for first installation which is on the installing CD-Rom which comes shipped with the printer and which I didn't have anymore.
I then let the installation run for my setup (wifi over router) and finish. Finally I tested the whole with My-Printer. As mentioned I did not unistall anysoftware previously installed.

I hope this is helpful for anyone with this problem. I needed to scan an item using the Canon MP Navigator. When I went to the program to start the scan, I couldn't find the icon on my desktop. I searched the computer and found the program, but it would not open. I went to the Canon website to download a driver, which had changed from the 3.1 version that I had originally, and downloaded the current file. I am running Windows 10. The download appeared to download correctly and I went through the dialogue to install the driver. Everything seemed to go well until I tried to open the program to start the scan. Nothing. I apologize, but I don't remember the error dialogue, but by then I was seeing red. I spent hours looking for an answer. I re-downIoaded the driver three more times, and each time I would get the error. You would think that the error dialogue would be burned into my memory, but alas. Finally, I decided to try the driver for the Canada version of Canon. I downloaded it, ran the driver and it worked! It is another version of MP Navigator, Version 3.15. My Canon MX870 is scanning just fine! I am pretty sure that the problem occurred due to a Windows update. Here is the link to Canon:
I hope it works for you.
