HI Eveyonestill wondering how i can install the pmdg 737 and 747 in the vistajust got FSX, and the right rams and speed, and it s just great. but i m missing the pmdg heavies. can anyone write me back here the how to...i tried every possible installation with adminitrator and user etc etc it just did not work for me . I run a Vista home edition, dual core 2.4, nvidia 8800GTS. other add ons are okay so far. i read some posts here where some folks are already running the 747 way before any update. Am I right? did i understand correctly? any tips?ThanksNasser

Nasser,Please see the Vista FAQ:http://ops.precisionmanuals.com/wiki/PMDG_Windows_Vista_FAQThe 747 and 737 are not compatible with FSX if that's what you're asking. They're for FS2004. There will be FSX versions released at a later date.
