Urgently required: activation is stored in which file.

I am using NIS 2013, I activate NIS through internet whenever i need to reinstall.

But after 8-10  days i.e. May 30, my internet connection will be disconnected because i am not able to afford my connection cost.

 

I require which information regarding activation.

When i activate my NIS through internet, product activation is stored in pc also.

Can you please tell me in which file activation information is stored.

So the i will copy that file and replace it with in future.

 

Without internet i can use my NIS.

I don't want to loose my NIS subscription days.

 

Can anybody help me in getting the solution. I need urgent positive information.

So to avoid future activation problem (without internet).

 

Thanks

Mike.
