Just recently replaced my old laptop with a desktop. Windows 7 64 bit, AMD Athelon II 255 3.1 Ghz processor, 5GB ram ATI 5770 graphics card, and 650 GB hard drive. Using FS2004. I have reinstalled well over 75 different sceneries from numerous vendors including FlightZone01 Rhode Is. with out a problem except for one. Reinstalled FlightZone02 from Flight 1 website without any indication that the software did not install properly.I start FS9 and then click to run KPDX. A windows box then pops up stating it cannot finish loading because of a problem. Thanks for any advice anyone could provide concerning this issue

The good news is that it does indeed work just fine under Win7 x64. The scenery contains a bunch of AFCAD files - you might check and make sure that none of them duplicate existing AFCADS in your scenry collection. I believe that there are also some possible conflicts with UT and FlyTampa Seattle, but I don't recall those causing CTDs.DJ
