I have the Following REQUIREMENTS it requires to run: FSX SDK to use SDE if you wish to compile bgl files. You do not need
it if you just wish to explore Scenery Bgl files. The SDK is not freely down loadable and is
supplied by Microsoft only with the deluxe version of FSX. SDE uses components of the
SDK and you must have these for the program to work compile
● Microsoft's dotNET 2.0.
● You may need other software such as MSXML if not already installed.
I have Microsoft .NET Framework 4.5.2 installed on my system. is this the same as.Microsoft's dotNET 2.0.
