Hello, is it possible to install just the 800/900 without touching the 600/700 settings, or what is the best way to back up my 600/700 settings so I don't have to go through a complete reinstall if I need to after installing the 800?regards Robert

No it will not work since the GAU file is updated. It's really impossible to have both like this. Don't you still have your original 600-700? It's much easier to reinstall if you happen to have issues otherwise you would have to save every single file in all folders from MODULES/AIRCRAFT/PMDG/GAUGES and any others you might find, much to much IMO.[h4]Best Wishes,Randy J.

Yep I do have the original and that's what I have reinstalled.As my frame rate were smashed when I installed the 800 and it was a pain to reinstall everything again that's why I asked this questionregards Rob
