I have purchased Nikon Coolpix P510 camera and when i tried to connect to my windows 7 64 bit machine it says "MTP USB Device" failed to install message.
I have already installed "View NX2".
How can i resolve this?
Are you logged in as an administrator account on your computer? If not, I'd login as admin and try again. If it fails, try plugging into another USB port on the computer.
You might also want to check that you have the latest version of View NX2 (which seems to be 2.3.1 - probably doesn't matter for this problem, but the version that came with the camera may not be up to date)
Do you have the 32b or 64b version of View NX2? If you're not sure:
If you can't get the version you have to work, you could try installing the other version.
If that fails, try going through the camera menus and setting transfer mode to "Mass Storage" or "PTP".
