Recently switched from Windows XP to Windows 7 and have a PIXMA MX-870 multifunctional printer. When I try to open the solutions menu I get an error message " Cannot start MP Navigator EX check 1. Supported model is listed MX870, MX340, MX350 Canoscan 9000F 2. MP Driver/scanner driver is installed 3. Your product model is connected to PC properly and power is on 4. Reconnect the USB cable when connected with
My printer is online and I can print, but cannot scan from the solutions menu because get Cannot start MP Navigator EX message
I checked the forum references to MP Navigator EX stopped. Checked the Twain_32 folder. Only had one file (wiatwain.ds) in the folder there was no Pixma MX 870 file or any other files in that folder.
Have reloaded files from original Canon software disk and have updated Canon file drivers, etc. but get the same message .
Where do I get the Pixma MX 870 file to put in the Twain_32 folder and should that fix my problem of not being able to open MP Navigator EX?
Appreciate any guidence about how to fix this problem from the forum.

The TWAIN drivers are installed at the same time the printer drivers are installed. Since the PIXMA MX870 folder was not in the TWAIN_32 folder and you experienced the same issue after reinstalling with the disc, we can install the latest drivers and version of MP Navigator from the Canon USA website to try and resolve the issue. The following link will take you to the initial download page for your PIXMA MX870:
Once on the initial download page for your model, please do the following:
1. Verify that the operating system detected in the "OPERATING SYSTEM" drop-down menu is correct, and if it is not, please click the drop-down menu to select your operating system.
2. Next, please click on the red arrow next to the "DRIVERS" section and click the MP Drivers file. When you do, another page will appear giving details of the file you are about to download will appear.
3. Please scroll down on the Details page and agree to the terms of the disclaimer message to continue with the download process by clicking on the "I AGREE - BEGIN DOWNLOAD" button. After clicking the "I AGREE - BEGIN DOWNLOAD" button, follow the instructions to download and install the driver. The time for the download process may vary depending on the speed of your Internet connection and the size of the file being downloaded. Please be sure to have the USB cable unplugged from the computer prior to installing the drivers; the installation program will prompt you to plug it in at the appropriate time.
Once you are done reinstalling the drivers, please follow the steps above to also re-install the MP Navigator program on your computer, except for you will want to click on the red arrow next to the word "SOFTWARE" instead of "DRIVERS" in Step 2 to locate and download the MP Navigator program. After all of the drivers and software have been installed, please restart your computer and attempt to scan.
Hope this helps!

On Win 7 64bit, mp navigator cannot start. The canon files seem ok in twain_32.
I've reloaded the drivers and mp navigator fron the canon site. All printer functions work except scan.
Thanks for your help.

Are there any other files in your TWAIN_32 folder other than the files related to your printer and the wiatwain.ds file? Also, what printer model do you have?

I tried the various options without any luck until I contacted customer service and they gave me the help I needed to correct the problem on MP Navigator EX not opening. Give them a try.
