Oh yes, I hit that problem, and figured the work around. There's a two-stage installer. The first stage, which just presents some options and neat buttons on-screen, is what it broken. Go to the directory contentsoftwareamapi3d and you'll see the first-stage installer there, with a file called TGSFront.ini Go into the Amapi3D directory and run the setup.exe you find there. There's a couple of plugins in other directories for 3DStudioMax and 3space. I suspect that there's some cort of messup over EOL sequences.
