M-Color is only impacted when using the AutoCAD Application.

  • AutoCAD Version: 2018
  • M-Color version 9.9


3     Symptoms

M-Color works as expected. M-Color menu in AutoCAD fails to work and ??? or greyed out for the buttons. In AutoCAD when attempting to use the M-Files plug-in, the buttons do not work and have ??? or are greyed out.


4     Cause and Reason

This can occur when either of the AutoCAD or M-Files is updated.

Either they are missing files associated to menu items or the menu bar was not associated correctly when AutoCAD was installed/updated.


5     Solution / Workaround

In M-Color installation folder (usually C:\Program Files (x86)\M-Color), verify .arx and .ltx files for 2018 and 2019, are present.

If not, download the new M-Color installation package, uninstall and install M-Color again.

  7. If the M-Color 9.9 popup menu and/or ribbon does not yet appear
    1. enter the command MCO_MCOLOR_MENU on the command line in AutoCAD and press Enter.
    2. If this does not help, enter MCO_MCOLOR_MENU2 and press Enter. If the menu still does not appear, try the following:
      1. Close the AutoCAD and M-Color.
      2. As an Administrator, log on to the server machine to the profile that people are using to work with. Open the Windows Explorer and navigate to the path:                     C:\Users\[USERACCOUNTNAME]\AppData\Local\Motive
