When the problem occurs on a Windows machine, make sure you have disabled "controlled folder access" in the App Windows-Safety or allow folder access to your program. (must have administrator privileges)

below reasons can possible :

The sourceFileName or destinationFileName parameter specifies a file that is read-only.

-or- This operation is not supported on the current platform.

-or- Source or destination parameters specify a directory instead of a file.

-or- The caller does not have the required permission.

This exception is covered in the documentation for File.Copy:

The caller does not have the required permission.
-or-
destFileName is read-only.

Check the attributes of the file after the first copy. Are the permissions what you expect? Do you need your program to run elevated (as administrator)?
