What should I do if the Win10 system opens a CAD error?

Problem Analysis:
In fact, in the win10 system, when we encounter the problem of opening a CAD error and sending a command failure to the program, we can easily solve the problem by simply turning off the system LUA control.
Workaround:
1, use the combination key in win10 "Win+R"; open the run and enter "ldedit", press the Enter key, or open in the Start menu -> Programs - -> Attachment--> Run, also enter "ldedit" in the run window. Press OK to bring up the Registry Editor.

2, open the Registry Editor and expand:
HKEY_LOCAL_MACHINE --> SOFTWARE --> Microsoft --> Windows --> CurruntVersion --> Policies --> ;System.
Locate the “EnableLUA” option in the right window.

3, after finding EnableLUA, double-click to open, in the EnableLUA property window, modify the "value data" to ""0” and then click "OK", and finally close the registry, and finally restart the computer.
