Wait, I should check if AutoCAD 2007 even has a 64-bit version. Let me think. Autodesk started providing 64-bit versions in later releases. For example, AutoCAD 2013 for Windows was available in 64-bit. So 2007 might only be 32-bit. That's critical. The user might be misled in this assumption. I should clarify that and inform them about which versions are truly 64-bit.
