Recently I placed Fs9 and FSX on the same computer as a new installation. Followed the instructions per David Marshall for a Win 7 64 bit system dual installation. I have to say that the Fs9 side operates great but my computer was simply not up to the task of operating FSX from a performance perspective. I reinstalled FlyTampa TNCM, KBOS, VHHX, and KBUF both for FS9 and FSX. I now have multiple scenery library listings for those scenery's in FS9. VHHX and KBUF are fully functional. KBOS will show only the default scenery and TNCM leaves me a "grass field" with no airport scenery in sight. Any help would be greatly appreciated concerning this matter.
