Return of Reckoning

So ive downloaded the game and everything unzipped into a separate file now but when i launch the launcher i get a error saying

Error unpacking:
System.UnauthorizedAccessException: Access to the path 'C:\Users\Swagmoney420\Desktop\Warhammer online\ICSharpCode.SharpZipLib.dll' is denied.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean checkHost)

at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share)
at RoRLauncher.MainWindow.Unpack(String fileName)

im able to close out of that then hit connect and it just crashes my launcher? i have the file set to read only. i have no clue what to do from here i also followed this video https://www.youtube.com/watch?v=Bn_75A_-RYg
