Install Collabora in self-hosted owncloud

Hi, I'm talking from Brazil. I work with reseller website hosting and installed owncloud through Softaculous.
From what I've been reading CollaboraOffice CODE version is free to use, however I do not have access to the server's SSH to install it as per instructions.
Is there any other way for me to be able to install Collabora in my self-hosted owncloud?

You could use the ownCloud appliance.

What exactly is not working?
