[Forge 1.7.10 - I HAVE RUN 1.7.10 MANUALLY AT LEAST ONCE!!!]

Hello,

 

I'm a half newbie, half not, but I have a question.

 

When I use the 1.7.10 FORGE WIN installer, this little guy comes up every time I press 'install'.

 

 

            |                                            Error                                                |

            |                                                                                                    |

            |    You need to run the version 1.7.10 manually at least once      |

 

 

I have run minecraft 1.7.10 at least once, and I tried resetting my .minecraft folder, yet still nothing.

 

Thanks, I always love to see helping hands in my nooby adventures.
