Do I need the CD in my PC to run FSX?

[Hotshot]

I had always thought not, and there's no reference ito this in the supplied handbook, but after a trouble-free month of flying my FSX has taken to crashing when I change airfields, and visiting the Microsoft FSX website for the first time, I find FSX listed among the MS games which do demand the CD. Could that be the cause of my problem? Do you guys use the CD??

[Clipper]

Just wondering...how did you install FSX without the cd?

[Hotshot]

I said 'to run,' not 'to install.'

To run it NO ...... but only if you have activated it properly.

[alan52]

in simple terms no.

If you have activated your FSX, then you do not have to use the CD to run FSX  :D

[KDSM]

you have the demo?
