Cannot move the temporary zip file to the real zip file destination specified by the ZipFilename property.
When zipping, and the UseTempFile property is set to True, the library creates the zip file in a temporary file. When it has completed the operation, it attempts to move the temporary file to the destination zip file. A copy is made if the source and destination are on different drives. This error can happen when the application using the library does not have the permissions required to delete the destination zip file, even though the library was able to open it for writing before the operation started as a check to avoid this type of error...
