Unkown error: "failed(1004)"

[Ape]

What is that error? I have a function that runs all the time in my computer. It crashes sometimes, but I make the code better so it tells the details and keeps going.

This is rather rare error and doesn't affect to anything.. I can't show the code, but I can tell that I use IntGetFile very much. Can this be the reason?

error code :1004
error description :failed
error iid :7
error line :
error place :7076
