Hi
Had the same issue. Clicking on Manual Download button triggered a JS error (seen in the browser console), complaining that the `utag` object isn't defined. I've inspected the JS script at that line and found the link below [1]. Opening the link in another tab showed a JSON object [2]. Opening the "popupurl" link allowed me to download the ISO file.

popupurl "https://download2.vmware.com/software/esx/67u3/VMware-VMvisor-Installer-6.7.0.update03-14320388.x86_64.iso?HashKey=da*********" openmodal "no" popupmode "manual"
