AutoCAD 2015 Application Error (0xc0000142)

Fixed from Registry

After the installation of AutoCAD 2015 on a PC, when try to start it, Application Error (0xc0000142) happened and AutoCAD won't start.

This may caused by various reason, but I fixed this error (one of my installation) by the editing of registry. Follow the steps below, if the registry key LoadAppInit_DLLs value is 1, change it to 0 will very possible to fix this problem.

  • Run 'Regedit' and open registry;
  • Find the key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\LoadAppInit_DLLs
  • Change the key LoadAppInit_DLLs from 1 to 0;
  • Close 'Registry' editor.

If the key value is 0, the error may caused by other reason.

(Edit registry with care)
