About 64-bit USEARCH
The 64-bit version of USEARCH can use all of the installed RAM in a 64-bit computer, while the 32-bit version is limited to at most 4Gb allocated memory. See memory requirements for more information.


One license allows you to run one copy of USEARCH, meaning one process. It does not allow a user to run more than one process at one time; for this you need multiple licenses. The license may be shared in a group, e.g. a lab, providing that no more than one process is running at any given time.

The license is a one-time fee which includes technical support and an upgrade to the next major version (the major version is the first number, e.g. the major version of  v7.0.1234 is 7). Minor version updates are provided at no charge.

You can use this page to purchase one license. If you need more, let me know and I'll send you a link to a custom page for your purchase.

When payment is confirmed by paypal, I will email you a link to download your 64-bit build of USEARCH. Please allow up to one business day for delivery.
