FS9 Update question
Posted: Wed Oct 19, 2005 11:59 pmIf I install FS9.1 update will I lose flight environment and will it make any changes to my payware aircraft (sounds, panel, etc.)??? I have the update but not sure if I should install it. 
It won't affect your payware aircraft and sounds.
It's mostly for the FS9 engine and the scenery to replace missing bridges, fix airports...etc.
However you should make a backup in worst case...
If you have the no-cd FS9.exe, it won't work in the FS9.1 after the update. There is a no-cd FS9.1.exe out there but don't ask for it on the forum, the mods have a problem with it.
