| Your Scenario | Recommendation | | :--- | :--- | | | Use Lumion 11 (legit student license is free for 1 year). Avoid v8-9 – too outdated for portfolio work. | | Freelancer on old PC (GTX 1060/1070) | Stick with Lumion 9 or 10 if you already own it. Do not buy a license for it now. | | Professional firm with active projects | Avoid older versions. The lack of customer support, Windows updates breaking it, and file incompatibility will cost you more time than the subscription fee. | | You found a "verified crack" online | Do not install. The risk of ransomware or render farm backdoors is extremely high. Lumion cracks are among the most infected software types. | | You need to open an old Lumion 8 project | Install Lumion 8 on a Windows 10 offline VM or old laptop. Never connect to internet. |
