Question Assistance Installing 3rd Party SSL Certificate

Hello all,

I'm new to manually installing SSL certs, but given recent issues I've had with Plesk auto-renewing Let's Encrypt SSL certs, I've had to go this route. I have two domains that I have purchased SSL certs through the domain registrar, Network Solutions. We didn't purchase through Plesk because, well, internal politics with the company. Anyway, the files I've downloaded are all .CRT files - one with the domain as a file name, a Root SSL DV cert, and two intermediate CA certs. But, when I go to install them in Plesk, it requires a Private Key file as well which was not provided.

So my question is how do I go about installing the certificate with these four files? Do I need to convert one of these to a Private Key file? And with the two Intermediate CA files, do I just pick one and somehow either rename it or convert it to a .ca-crt file? Again, keep in mind this is something new to me. Thank you!

Could you please check the .crt files with a text editor and confirm if you see a section such as -----BEGIN PRIVATE KEY-----?

And this video might be of use too (from a different certificate provider, but the prosses should be pretty much the same).
