If you don't see this domain listed within the options to install to in Softaculous, this means that you have not added it to your cPanel account. After adding the domain as an addon domain, you will then see the option to install to it available.
I have the domain created, but it still does not show up.
Site was built in a different server (as all as my other ones) and I have just the files here. WP was not installed here. Is this the problem?
I guess this is not enough. I have all domains added, but only the ones that were installed with softaculous show up. I have talked to them, but I keep geetin the same answer: add this code in the comand... but there is no option in our softaculous. Maybe in the remote one.
So, same question: how to have already added domains to show up in the sofculous.
Domains are with another server. They point to InMotion server. Here, we just have folders (now individual cpanels) . There is a way to add these site inside softacoulous. At least they at softaculous told me so. But they keep sending instructions that don't apply tour our version of softaculous.
