When I try to export a PCB as a DXF or DWG, I get an error with the following details: Class not registered at ###... SaveDxf.dll, Base Address: ###...

To resolve the Class not registered error, please close Altium, then try reinstalling or repairing TeighaX by running C:\Program Files\Altium\AD[version]\System\Installation\TeighaX_Setup.Restart Altium Designer then retry the export.
