If you want to push all the tS7 interface stuff out of the way and get to something familiar, there's a trueSpace 6 button near the top. Hit that and *ZIP*, you're looking at pretty much the default trueSpace 6.6 environment.
Now I just need to find where to disable the 3D widget and Magic Ring, and where to make new primitives pop up "On Grid" at the origin. I hope it can import workspace configurations from tS 6 because I have 6.6 exactly how I like it on a 19" widescreen LCD.
I downloaded the 7.6 installer and the manual and video installers. To save space but keep the manual handy, run the manual and video installers then burn the PDFMan folder and all three installers to a CD-R. Now you have a disk you can use for the manual and install just trueSpace 7.6 on your PC. That saves 213 megabytes of space.
So, MS bought Caligari eh? "Windows *VersionAfterVista*, now with full-featured 3D modeling and animation software built in!", followed by lawsuits from the people who bring us Lightwave, Maya, etc...
