I need the offline one because my company won’t let us install it via download, and they won’t use the GIT package. In order to get this do I need to purchase a user seat for this first, is that why it won’t appear?

Tell them to tell admin to install that software for you.

It is usually admin that makes such security rules, so let admin deal with consequences of his own security policy. That is best way to make admin understand his own security policy.
