I'm having similar problems. My collaborator who needs to view Inventor models tried unsuccessfully installing Autodesk Inventor View 2013, specific problems not identified. I downloaded and tried installing it myself on a computer of mine (not running Inventor), and after what seemed like a successful install with only a comment about some component not installed, I see absolutely no trace of the program. My Win7 64-bit control panel shows Microsoft .NET Framework 1.1 and Microsoft .NET Framework 4 Client Profile installed, the latter with a 2011 installation date. I have trouble believing that this is too new for AIV 2013 to work - is that what your solution is suggesting? Any thoughts on why after the installer did indicate a successful installation do I see no program installed?
