We purchased some time ago licenses for the Intel MKL libraries (OS X and Linux) through a 3rd party reseller, who gave us the serial numbers. We used the provided registration urls (https://registrationcenter.intel.com/RegisterExpress.aspx?sn=XXXX-XXXXXXX w/ XXXX-XXXXXX being the license), which worked fine.
But we would like to consolidate those products to a single account (the one associated to the account I am using in this forum). The problem is that I do not know which account those were associated to originally. What options to I have to recover that account (at least the account id) ?
