Orbx London City in update 1.13.16.0

Just about to reinstall the London pack and wondering the best way to do it?

1)when you talk about using the pack with or without the photogrammetry what do you mean? - seem to have (in the orbx software) a configure button that lets me run the landmarks with or without the UK world update? (is this what you mean?)
2)when you talk about disabling the photogrammetry for the UK - do you mean there is(in the downloads section) a separate photogrammetry download for the uk that you can uninstall? or do you mean simply disabling photogrammetry in the graphics sections?
