Lumion 2023 Host File Entries Detected Patched

Some antivirus programs (especially Avast, AVG, and McAfee) falsely flag Lumion as a threat and modify hosts entries as “protection.” Temporarily disable real-time protection during installation, then add Lumion’s entire folder to the exclusion list.

They will typically look something like this:

127.0.0.1 backup.lumion3d.net
127.0.0.7 www.lumion3d.net
0.0.0.1 support.lumion.com

Action: Delete any lines that reference Lumion or Act-3D domains.

Note: If you see entries for other software you no longer use, you can remove those as well, but be careful not to delete entries you don't recognize if they are part of a specific network configuration you need.

Newer Lumion versions check certificate revocation lists (CRL). If your patcher modifies the digital signature of Lumion.exe, Windows may mark it as corrupted. You'll need to disable certificate validation via gpedit.msc (not recommended for beginners).
