/wp-admin/install.php redirecting to 123-reg

I’m Nerys, I work here at 123-reg. It does indeed sound as if your domain name has not been pointed to your hosting package. Your hosting provider will be able to provide you with the details on the records you need to set up. This will usually be changing the nameservers, or setting an A record. I have included links to guides for setting up both of these below:

Nameservers:

A Record:

If I can be of any further help please do ask.
