I have this same problem o a English installation of Inv 2011 Simulation. The Stress analysis button does not exist and also the help button does nothing. This was installed on a new installation of Vista X64 that had no other software installed except for MS Office 2007. I have tried a repair installation and have the same results.
We had the same issue with the help on a 2010 installation on another machine that was reported numerous time and was never resolved! please help..
Hi,
first, please make sure you installed AIP or Simulation.
please launch Inventor, Tools->Add-ins, check if those three Simulation add-ins are loaded. if not, load them on start up and re-launch Inventor, see whether the problem solved or not.
if that still doesn't work for you, I afraid you have to register the simulation files under Bin foder manually or reinstall Inventor.
about help problem, please check if file ADMMain_15 exist in ----\program files\Autodesk\Inventor 2010\Help, if not, you can copy it from source DVD into that folder.
