Greetings,
The drivers available for W7 are mature and should function without issues on windows7 (32 or 64bit).
Why it won't run in your environment, we can only speculate.
-Problems with your OS or file system
-3rd party Anti-Virus or software firewall
-Hardware or drivers issue
-Problems with the device itself
-Cable or connection issue
-Problem with your installation media
-Using old installtion media
Things I noted.. you are trying to install MP Navigator v1.0
Version 1.08 is avaiable on the Product support page for your device
I would suggest downloading the latest version of the installers for your OS from the 8800F's Support Page
Drivers Tab / Software tab.
These however, may only be a short term solution.
Windows 7 is about 45 days away from being EOL.
Its time for you to consider a new OS. Your scanner will continue to work with Windows 10, and you'll be a whole bunch safer too.
Good Luck 🙂
