How to fix the corrupted classic-ribbon.cui file at BricsCAD startup?

Symptoms

When I try to start BricsCAD®, an error message displays:

Xerces Error - Fatal Error at the file...

Clicking the Yes button opens the program but there are no menus available except for File that has Menu under it.

Cause

Something went wrong with the customization file. The classic-ribbon.cui menu file in the user folder is corrupted.

Solution

There are multiple methods to revert to a default working version of this file:

Method 1:

  1. Start BricsCAD®.
  2. Type CUI or CUSTOMIZE on the Command line.

    This should open the Customize dialog box.

  3. In the Customize dialog box, click the Manage your customizations... button.

    The Manage customizations dialog box displays.

  4. Click the Revert to defaults button.

    This replaces the CUI file with the clean file from the UserDataCache.

  5. Click the OK button on the Manage customizations dialog box.
  6. Click the OK button on the Customize dialog box.

Method 2:

Use this method only if no customizations have been made.

  1. Rename the Support folder:

    C:\Users\%UserName%\AppData\Roaming\Bricsys\BricsCAD\V25x64\en_US\

  2. Restart BricsCAD®.
