We purchased 1 MKL license in 2010. We have the serial number but at this point we don't know if it expired. How can we find out if we are eligible for upgrade or we have to buy a full license?
Sure, you can refer to the article at: http://software.intel.com/en-us/articles/how-do-i-manage-my-licenses for information. If you still cannot, please let me know.
