You installed an old LibFredo6, but a newer Fredo6 plugin (e.g., RoundCorner v3.4) is asking for a newer library. You must downgrade the Fredo6 plugin itself to a version that matched your LibFredo6 era. Find the companion old plugin versions.
If the bell continues to signal an update even after you have updated everything: : Modern instances require LibFredo6 v10
The search stems from a common pain point: automatic updates or manual installation of the newest LibFredo6 (v8.x or higher) often requires SketchUp 2021+ or specific Ruby API changes. If you try to load a modern LibFredo6 in an older host, you will receive syntax errors, missing class errors, or a complete failure to load.
The first version ever published of LibFredo6 was version 3.0. These early versions (roughly up to v9.x) were designed for much older versions of SketchUp, such as SU5, SU6, SU7, SU8, and the early 2013-2016 releases. They used a simpler installation method that often involved manually copying files into the SketchUp Plugins folder. These versions are now considered "frozen," as Fredo6 no longer develops or updates them to maintain compatibility with newer operating systems or SketchUp releases.
A: SketchUcation usually hosts the latest version, which is backward compatible with older SketchUp versions (e.g., 2017+). It is recommended to use the latest version available on the site. | | 14
A: No, LibFredo6 is a free library required to run Fredo6’s plugins, though many of the plugins themselves (like FredoCorner) are paid extensions.
Newer versions of Fredo6 plugins require updated LibFredo6 libraries to function.
