Not necessarily. The message itself is from Lumion, not a virus. However, if you did not manually edit your hosts file, you should be concerned.
Lumion 2023 includes a security check during startup. It scans your hosts file to see if any of its official server addresses are being blocked or redirected.
If the software finds these entries, it labels the file as "Patched." In the context of software, "patching" often refers to modifying files to bypass security. While you may not have "patched" anything yourself, the software has detected that the hosts file has been altered in a way that blocks its connection.
Once the file is open, you will see lines starting with # (these are comments and are safe) and lines starting with IP addresses (like 127.0.0.1). lumion 2023 host file entries detected patched
Look for any lines that contain the words Lumion, Act-3D, or license servers.
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. Not necessarily
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.
Early patches for Lumion 2023 only blocked the old IPs. They didn’t account for the new fallback license servers (e.g., license.lumion3d.net is now mirrored to license2.lumion3d.net). If your patcher is from January 2023, it is obsolete.
Lumion 2023 includes a sophisticated anti-tampering mechanism. Unlike older versions, Lumion 2023 actively scans the hosts file during startup. If it finds any redirection rules pointing to localhost (127.0.0.1) or invalid IPs for its activation servers, it flags them. Action: Delete any lines that reference Lumion or
The word “patched” refers to modified executable files (.exe or .dll) that bypass original code signatures. Crackers often provide a “patched” Lumion.exe that disables online checks. However, Lumion 2023 now cross-references the patched file against the hosts file. If both modifications exist, the error triggers.
In plain English: The software has detected that you are using a cracked version (either via a modified hosts file or a patched executable) and is blocking your access to prevent unauthorized use.
