Alejandro Fernandez 2025-12-12 20:15 Hi Freestyler,I hope you don’t mind me reaching out.I’m trying to install Orca3D v3 for Rhino on Windows, but I’m hitting Windows Installer restrictions/errors (it keeps blocking the MSI / saying the package can’t be opened). I’m not looking for any cracked or unofficial files—just a legitimate way to get v3 installed properly.Do you know the correct install path or any common fixes (e.g., prerequisites like specific .NET version, Rhino version compatibility, offline installer vs web installer, or licensing/activation steps) that usually solve this?If you have a recommended official download source or a checklist that worked for you, I’d really appreciate it.Thanks a lot,Alejandro Reply Toggle Dropdown Reply: Submit
