I have tried countless times to install Inventor Professional student version 2012 and something always goes wrong...I have tried all types of downloading/installing as well as in GoogleChrome and Firefox. The latest problem during my install was this...
CRC failed in x64\Inventor\Program Files\Autodesk\Inventor 2012\Bin\Bin32\AecModeler60.dbx
Unexpected end of archive
Problems downloading the Autodesk software and/or CRC errors may be avoided by using another web browser, or using the alternate browser download method.
