Search for the file, and either move it to the location specified, or re-specify the found location in the Tools > Options > System Options > File Locations section.
When at the screen in your image, when you click on the Configure button and select option 2, do you see something like the attached image?

If that doesn't work, then a complete clean uninstall and re-install may be required.
