SP1 Installation problem

[Davoos15]

When installing SP1 i'm getting a message saying "The feature you are trying to use is on a cdrom or other emovable disk that is not available.

Inster the 'Microsoft Flight Simulator X' disk and click OK."

Is that supposed to happen? Do I put in the FSX disk?

I thought you had Acceleration on your FSX already ?
If this is the case, you DO NOT need to install SP1 or SP2, because they are both already included in Acceleration.
