Well, he said this: "then I downloaded it and tried to show how to download it" Sounds to me like he downloaded it. Yeah, I heard the Lumion 9 scam trashed/erased hard drives. Don't really believe that happened. That's one reason I use macOS... Don't hear about much malware or viruses for us Mac users. Millions for Windows... If there was a legit download for Vray, Windows, I would give it a try with my Win 10 Virtual Machine. If it got magically erased, I have a backup. LOL Only then would I install on my "real" Windows 10 Enterprise. Even that too I have a clone. My Mac runs Windows and Linux like a champ. Show me a real download and I will test it.
