I just uninstalled my Acceleration pack because of problems with certain add-in aircraft.My first question is must I now download and install SP1 & SP2?Second, is there a way to tell if these programs are already installed?Finally, is there a way to remove the programs if necessary?Appreciate any and all responses.Jim

Id like to know this as well...if I'm starting with an unpatched FSX freshly installed do i need to install both SP1 & SP2, or just SP2 without SP1?...i dont own or want "Acceleration".Dave

SP2 requires that you install SP1 first. Only if you have Acceleration can you skip installing SP1 as it's included in Acceleration.http://www.fsinsider.com/downloads/Pages/F...rvicePack2.aspxRegards,Jim Karn

Thanks for the info Jim!
