Return of Reckoning

I downloaded the game again but it still doesnt work. I put RORLauncher.exe in the folder with game
I have the same problem :
Error starting: System.UnauthorizedAccessException: Acсess denied
"F:\Games\Warhammer Online - Age of Reckoning\WAR.exe".
in System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
in 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)
in System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolean bFromProxy)
in System.IO.FileStream..ctor(String path, FileMode mode)
in RoRLauncher.Client.patchExe()
in RoRLauncher.Client.Handle(PacketIn packet)

Sorry. I solved my problem by removing point on "Only for reading" in preferences of folder.
