The developers make a lot of changes to their versions of EA, I buy one version of EA, and in a few months this product changes significantly after updates are made.

I need to install-activate EA on another computer win10, but this is no longer the EA that I bought.

What should I do? How to install the previous version of the product for which I paid my money?
