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: ###...
Solution Details
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.
