Hi, I downloaded AutoCAD 2013 for Windows 64bit, installed it. But when I run it, it shows up an error window saying “The configured Heidi driver cannot be loaded. Switching to default software driver“. And when I try to change the view from the objects with the cube located in the superior right corner the same error shows up  saying “Error loading Heidi Module -C:\Program Files\Autodesk\AutoCAD 2013\Drv\acaddm11.hdi“.

I’ve searched everywhere for a solution but I can’t find anything. If anyone knows how to fix it please tell me.
