Your CD drive or DVD drive is missing or not recognized by Windows or other programs, so you cannot play or access a CD or DVD. This issue might have occurred after you installed, uninstalled, or updated a program or Windows Vista.
This problem is caused by two Windows registry entries that have become corrupted. To fix the problem, you have to use Registry Editor to delete the corrupted Registry entries. To use this method, you must be logged on to Windows as an administrator.
