Hi Masoud, you would need an Intel® oneAPI license to get access to the older versions of the product. The free download website only provides the latest version of compilers available at any point of time. To purchase a license, please contact your nearest re-seller/distributor. They would support you throughout the purchase process.
To contact your nearest re-seller/distributor, please click here: https://software.intel.com/content/www/us/en/develop/tools/resellers.html, and scroll down to select your country from the drop down menu. You will be presented with their contact information.
