ZetaLongPaths.ZlpFileInfo(_Path).OpenRead() not work on windows 8.1

[MustafaDaoud90]

string _Path = "LongPath";
System.IO.FileStream oReader = ZetaLongPaths.ZlpFileInfo(_Path).OpenRead();
not work on windows 8.1 almost return 0 bytes when read and when call windows error after this line return error (183) meaning:
ERROR_ALREADY_EXISTS
183 (0xB7)
Cannot create a file when that file already exists.

Note: the writer works fine on the same long path.

the same code works fine on the short path.

what is the problem?

ERROR_ALREADY_EXISTS usually indicates a permission issue (not enough permissions because of ACL and/or write-protection flag).

Please provide a MCVE.
