>msxml.msi is an installer, so you should not see text. So does this mean it should actually be an .exe file and for some reason isn't or what? The installation instructions do say there should be an msxml.exe

>So does this mean it should actually be an .exe fileDon't think so - msi files are microsoft installers. They *ARE* executable. It installed just fine on my machine, so i'm not sure what else to say...did you install the .net framework first?

Correct on the excluding. You might place the new bgl in the same folder as your third party scenery, thereby, making it at the same priority level as the third party scenery bgls.In most cases, placing it in the Addon SceneryScenery folder could cause the new bgl information to be excluded by higher priority scenery.W.

Pleased to say that there are no problems adding objects to addon scenery.(subject to layering correctly)Dave
