First even though i'm and old user. The computer I'm installing to never had RTMM installed. Yesterday I downloaded and install ever thing new. My question regards the library structure. I have attached a file with my structure. I have the 7 library files in the RTMM Objects Library folder. Misty folder in the RTMM Misty Moorings folder. My P3D V 4.5 scenery library only shows RTMM Required FSXP3D Libraries Part IV. Can you show me a break down of the libraries and what files should be in their libraries.Sorry but I can't attach the file I created.Thank YouBill McCracken
