Resolving the "The application cannot start...." warning

[face_off]

OctaneRender for ArchiCAD plugin versions versions prior to 2026.3.0.126 installed the Octane support files in C:\Program Files\GRAPHISOFT\Archicad [version number] folder. ArchiCAD now pops the following warning if it detects third party files in this folder.

The plugin installer from 2026.3.0.126 onward installs the Octane support files in a different folder in order to stop this warning from showing each time you start ArchiCAD. However you will still need to delete the prior version Octane support files in this folder. To do so, go to the C:\Program Files\GRAPHISOFT\Archicad [version number] folder and sort the files by "Date modified". Then delete the following files (which should all have the same date).

If there is any doubt, you can re-install ArchiCAD.

Thanks
