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.
If the key value is 0, the error may caused by other reason.
(Edit registry with care)
