[Error]
Quitting game when using a resource pack results in Error on Launcher.

• Game ended with no troubles detected (exit code 0)
• Deleting C:\Users\John\AppData\Roaming\.minecraft\versions\1.6.1\1.6.1-natives-467409725384321
• Couldn't delete C:\Users\John\AppData\Roaming\.minecraft\versions\1.6.1\1.6.1-natives-467409725384321 - scheduling for deletion upon exit

[Workaround]
• Manually delete folder in at designated path.
• Launch Game
• Yay Fixed! (until... Next time...)
• Q.Q

[Possible Fix]
• Permissions issue (elevate the launcher to a trusted user)
• Ensure code reflects deletion after Process ID has cleared (aka Minecraft being closed before Deletion takes place)
