The problem is I have done complete removal of Inventor 2008 as far as in the registry. Then reinstalled (clean install) and get the error and it will not load the ADMS. I have also do a clean removal again and did a clean install of 2009 with the same result as listed above. For some reason the computer will not see or recognize ADMS and allow it to install. I had no problems with it on my old computer running XP. I also don't have any problems with AutoCAD 2008, Architectural 2008, Revit 2008, 3D Studio Viz 2008 and Max 2008. So why am I having problems loading all of Inventor 2008? Since I teach this and need to be able to have my students ready for the Autodesk certification tests I need to have this active. Again I am running out of ideas and Autodesk has not been any help. I have not gotten any responses from them on their forums or from other contacts.
