Second, I install the aircraft and follow the directions on how to install and still when I load the aircraft things don't show up. For example I installed properly the fsx updated sr-71a blackbird and when I load it details such as the cockpit guages and panel don't show up, on the outside the flames that are supposed to come out of the aircrafts engines don't show up, all I see basically is the model of the aircraft, minor details don't show up but it can still fly and still has all the physics. I put the files that needed to be installed to the effects and guages folder in there. What's wrong with this, it didn't happen in flight simulator 2004 and it was much less confusing to install aircraft. It's not a problem with my computer and it goes way beyond the recommended system specs for fsx.
Also with updated aircraft, do you need the original aircraft and to update it with the new one or can you just install the updated aircraft and delete the old one. Sometimes it works the other way where you can just delete the old aircraft but not always. If you have to update the old one with some new files from the updated one, how do you do that.
I tried following the directions that come in the text document but either the aircraft doesn't show up in fsx or details on it are missing. Most of the time it's just the burner effects in the back of the engine that don't show up even though i installed it correctly.
