We have received several reports regarding AmMgdInterop.dll error messages when starting AutoCAD Mechanical 2013, while starting AutoCAD Mechanical 2013 with AutoCAD profile works fine. The development team is currently investigating the issue.
A procedure imported by ‘AmMgdInterop.dll’ could not be loaded.
At this time this issue mainly occurs on XP 32-bit and Windows 7 32-bit systems and contributing factors are having AutoCAD Mechanical 2013 installed ‘side by side’ with Mechanical Desktop 6, AutoCAD 2002 and AutoCAD R 14. If you happen to have Mechanical Desktop 6, AutoCAD 2002 and AutoCAD R 14, you need to uninstall them to make AutoCAD Mechanical 2013 work as expected.
In some instances reinstalling all Autodesk Products as per following Technical Solution helped as well.
