B3. After installation, I don't see any scenarios listed, or I don't get any textures.

This problem usually occurs if you forget to restore the Orbiter directory tree when extracting the packages. When using WinZip or a similar utility to unpack the Orbiter packages, you need to activate the "Use folder names" option (or an equivalent option to that effect). After unpacking the Base and Textures packages, your Orbiter root directory should contain (amongst other things):

• The orbiter executable (Orbiter.exe)
• A number of subdirectories, including Meshes, Scenarios, Textures

If all files ended up in a single directory, you made a mistake when unpacking.
