    End If
End Sub

How can I resolve this?

Answer 1

Most of the time when you encounter this error it's either one of two things. These are easy to rule out as the cause so you might want to consider doing that before looking elsewhere.

1. You attempt to write a file to a directory that you don't have Permission for.

2. You are trying to write back an image that you still have open.
