uninstall - mmdbresolve.exe could not be removed

There's nothing special about mmdbresolve.exe. It just happens to be at the top of the deletion stack:
uninstall.nsi

Having run some testing I think this issue occurs because the uninstaller doesn't request elevation so it can't delete anything from controlled directories such as "Program Files". Running the uninstall from the settings dialog runs the uninstaller with elevated privileges, or you can manually elevate the uninstaller yourself using various methods.

WAs told this my issue was a duplicate of this and to continue here.
I was trying to uninstall wireshark 3.0.2 and keep getting the error that it cant find that exe is it running. I have looked and that file is not even on my pc. I have tried to reinstall on top, reboot, create a file with that name, and remove the wireshark folder from program files. This is on a win10 pc. I have also tried logging in as administrator, doing run as administrator etc.

Having the same issue. File not on PC, there is no take or process running with that name. Can we just have an uninstaller that will not ask for that process but will remove the program and all the registry keys please.

What happens if you create a dummy file with that name, does the uninstaller then complete?
