I spent over an hour looking for this too. I finally did get 17.6 located and downloaded without having to know a site ID.
Try this link: https://support.broadcom.com/group/ecx/productfiles?subFamily=VMware%20Workstation%20Pro&displayGroup=VMware%20Workstation%20Pro%2017.0%20for%20Personal%20Use%20(Windows)&release=17.6&os=&servicePk=522390&language=EN
You will still need an account on Broadcom.com ( I assume you already do have one.)
