This is a Generic Windows Error message that basically only tell you that an illegal Memory Call was undertaken.

It can be caused by corrupted code, or pre-empted code.

It is not "useful" other than to tell you that you are doing something "illegal" memory wise in your code.

For your info, i'am run procedure that i was code. In windows 8.1pro 64 single user, always come out that error. I cannot classify what coding i was make and make it error like that. when using in windows 7 pro 64 its ok. Can you explain to me more.
