Jim,
phase one covers the Scenery Libraries installation which you need for objects to show up in the scenery itself. For Misty's Place I think the EZ_1 and RWY_12 libraries will give you almost all of the objects. There are other libraries you will need but this will get you started and then you will know how to add the other libraries later.
Here is the cut n' paste for you:
Installing Scenery and Libraries in RTMM.
Jim,
I did this offline and then post it here for your information.
Scenery Libraries EZ_1.zip and RWY12_1.zip were originally written for FS9 (FS2004) and have .exe installer programs that, if you use the defaults in the installer will try to install the libraries into FS9 and not be in the correct place for our use. I almost never allow an installer program, either scenery or airplanes to install anything directly into FSX. (I do not trust where or what it may do) If the install has the feature to select where it is installed as most of them do I have a folder I named FSX Junk and direct all installers to that folder. That way I can see exactly what and where the installer is trying to place the library, scenery or airplane files. If they are directed to an FS9 install I can see where they would go in FSX and place them accordingly manually.
Most people have multiple scenery libraries such as EZ_1 and RWY_12 etc. etc. This is fine and allows for keeping the files separate. It is not necessary to have these separate libraries however and you can combine the files into one library which allows just one addition to the FSX Scenery Library. It is your choice.
I have a combined library in my FSX so I can not give you a 1, 2, 3, tutorial as I do not have the individual downloads any longer on my HD so this will be a how to but not specifically step by step for the libaries.
Normally when you run the installer it will result in main folder usually named for the scenery files like EZ_1 or some such name. In this main folder will be two sub-folders one named scenery and one named texture. The scenery sub-folder will contain mostly .bgl, .xml and .txt files. The texture folder will contain mostly .BMP or .DDS files. Just place the main library folder (EZ_1) with the two sub-folders into your FSX Addon Scenery folder. Start the FSX program and when the first screen comes up click on Settings on the left side of the screen and then Scenery Library. On the next screen you pick Add Area. The next screen will show your FSX folders. Double left click on the Addon folder, find the EZ_1 folder or what every you named the library main folder and then left click that folder ONCE then click OK. The library will then show up in the FSX Scenery Library screen. Keep it at the top of the list.
Next time we will do a step by step tutorial for adding Misty's Place and the sound files as well. For now this is enough to keep you guessing (LOL) and hopefully it will get those libraries into FSX for you.
