Hi @Anonymous ,

What is the value of DCTMAIN system variable?

You can verify it by typing DCTMAIN at the command prompt and hitting Return.

By default it is "enu":

Command: DCTMAIN
Enter new value for DCTMAIN, or . for none <"enu">:
Command:

If it is "enu" and you still get an alert from AutoCAD, try to set it for none by entering . (period) for its value.
