How can I get Enfold theme version 4.5.7?

Dear Support,

I have a website using Enfold theme v4.5.7, and now after upgrade WordPress to v5.5, I need to upgrade the Enfold to v4.7.6.3.

But in that old time, I didn’t use the Enfold Child Theme, and I can’t remember which files have been modified about the old version contents. Now I want one old-version copy to figure out the diff. and migrate them to Enfold Child.

Can you help me to do that? Thanks a lot!
