Hi Swapnil , Have you restarted your machine after disabling Communication Center in regestry? I have disabled Communication Center throug HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R18.1\ACAD-9001:409\InfoCenter\InfoCenterOn=0 restarded machine and ti did not start. IfCommunication Center start is disabled it could be a diferent reason of this issue. Regards, Artiom
