Hi @WillyMo24,
Only the latest two versions of the Creative Cloud apps are supported and available for download. You can try and download CC 2017 apps from the following website. If the links mentioned on the website don't work, then it means that Adobe has discontinued providing the download and genuine installers are not available anymore. Be circumspect if someone contacts you claiming to provide an installer in such a case.

P.S.:- I don't know how this would work(if it works) with an enterprise license. I don't have any personal experience with this license.
