Not launching any mods

[Sir Doddington]

So I open the technic launcher and click to play a mod and it doesn't launch. It downloads and processes the version but then nothing after that. This is happening with all the mods.This is what the console says;

java.io.FileNotFoundException: C:UsersJakeAppDataRoaming.technicmodpackstekkitmainbinnativesOpenAL32.dll (Access is denied)
