the SU 2023 (on win 11) install

@Tpdart said:

Any thoughts on a resolution please?

First update to SketchUp 2026. You must have an up to date SketchUp subscription since you are using SketchUp 2023 so you can update to 2026 at no additional charge.

Next, make sure SketchUp is installed correctly so that Windows 11 grants the required permissions to allow SketchUp to write the files it needs. Correct installation involves right clicking on the downloaded installer and selecting Run as administrator.

Make sure you have the latest version of the Sketchucation ExtensionStore installed and use it to install LibFredo6 and the other extensions.

Weirdly, in SU extension manager I tried disabling the libfredo extensions, saving changes, closing SU, reopening and the extensions are still enabled!!! Any thoughts on a resolution please? Thanks

Also, please quote the error message correctly.

Are you also saying that you use AdditionalPluginFolders plugin to install plugins in an alternative directory?

So, you need to purchase one.

How are you installing your extensions ?

If you are copying files from one SketchUp version's Plugins folder into another. then it's a recipe for chaos.

If you download them from our PluginStore as RBZs and then use the Extension Manager to install them, then they automatically install in your default Plugins folder, from which SketchUp loads any extension .RB files it finds at startup. In your case it's
C:/Users/MSonmez/AppData/Roaming/SketchUp/SketchUp 2026/SketchUp/Plugins

If you use the ExtensionStore's dialog to auto-install them, that works without the need for the RBZ step, but they default to install in the same default Plugins folder.
However, you can opt to have your own personal destination folder, chosen and remembered with the ExtensionStore's Settings > Paths option. It's really only useful for those with a centralized folder used across SketchUp versions - you need to set up this alternative path using Fredo's AdditionalPluginsFolder tool.

An alternative path offered might be the Plugins folder in the ProgramData path, but this is only used for extensions shared between several users on the same computer, unlike your own user's Plugins folder personal to your login: it's typically used by more complex extensions like renderers etc. It does load its .RB files before the default Plugins folder so it could explain the duplication, but why all of your extensions seem to have arrived in there is a very unlikely mystery. It's not normally listed unless some previous installation [like a renderer] has made the Plugins folder for its .RB and subfolder...

If you can check for multiple Plugins folders and their duplicated contents it will help. Try to ensure only one version of each .RB and it's matching subfolder exist in any likely-to-be-loading Plugins folder.

Running this text in the Ruby Console will give you a list of all file-paths that are loaded from - BUT only the default ../AppData../Plugings would be normally listed in the ExtensionStore's Paths, never put extensions into another of these folders, unless you are really sure of what you are doing -
$LOAD_PATH
Please report back...

1-C:\ProgramData\SketchUp\SketchUp 2026\SketchUp
2-C:\Users\MSonmez\AppData\Roaming\SketchUp\SketchUp 2026\SketchUp

I think this has been causing all the issues. I tried renaming the plugin folder (the one under C:\Users\MSonmez\AppData\Roaming\SketchUp\SketchUp 2026\SketchUp) to something different and now the plugins are loading.....
