Issue

When attempting to open F/X CAD or AutoCAD, you received an error message similar to the following:

Catalog File 'Support\AcFields.fdc' is Not Found. (Opening AutoCAD or F/X CAD).

 

CAD may start as it would normally, but you might be missing items such as ribbons or toolbars, plot style tables, and plotter configuration (PC3) files.

Cause

Your AutoCAD profile has likely become corrupt, resulting in this error message.

Solution

2. Navigate to the folder C:\Program Files\Autodesk\ AutoCAD 20xx\UserDataCache\Support (where 20xx is your year version of AutoCAD or F/X CAD).
