The GeoLiteCity.dat file has been moved to the AppData folder, so you should set the path to:
<add name="maxmind" type="EPiServer.Personalization.Providers.MaxMind.GeolocationProvider, EPiServer.ApplicationModules" databaseFileName="[appDataPath]\Geolocation\GeoLiteCity.dat" />
If the Geolocation folder doesn't exist you can just create it and copy the GeoLiteCity.dat file from the "Program Files..." folder.
Thanks, I thougth it was like that but was confused when there were nothing to be found under AppData
I have just upgraded a site to 7.5 where we are using this and I notised that the databasefile reference back to program files and 7.0
C:\Program Files (x86)\EPiServer\Framework\7.0.859.1\Geolocation\GeoLiteCity.dat
Is this function gone in 7.5?
