True view is a standalone viewer and has nothing to do with AutoCAD other than it allows you to view ACAD DWG files without ACAD and also will convert drawings to a different version.
I am a bit confusd with the last ssentence, though. If the installer does not work then Trueview is not installed so "... there's yer problem..."
After a successful install you should have a desktop icon that will open Trueview and allow you to browse to a DWG file you want to see. After you open it it should also have options for converting. If you don't get the desktop icon look thru the START > AUTODESK .... etc (don't know the full path) to get to the Trueview selection.
There won't be any launchers inside AutoCAD.
