[Plugin Library] LibFredo6 - v15.9b - 21 Apr 26

rmsnmz

today, all of a sudden, my Fredo plug ins stop working with error messages saying that a subfolder was missing. I reinstalled them all but now the Fredo library is failing to install. I tried uninstalling and installing again several times but same issue each time. These is the error log:

anyone is experiencing similar issues? Anyway to fix it?

fredo6

What is the message about the subfolder missing? I don't see it
Which plugins of mine do you have installed?
If you can start Sketchup with LibFredo6, could you invoke the menu Window > LibFredo6 Settings > Fredo6 Plugins Information for Sketchucation Support... and send me the output text which is displayed in the Ruby console.

Thanks

I probably have all your extensions but only a few shows up now because of the library is failing to install. As for the "sub folder" missing error message, that was the first error message i received and I basically reinstalled all extensions after that. Now, i dont get that message but just the message above regarding the fredo library part. Here is what i see in the Fredo6 Plugins Information for Sketchucation Support:

"Can not load Curic Helpper!"

rmsnmz

I suspect this has to the updated skecthucation toolbar. I now have two active plugins folder all of a sudden.

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.....

TIG

All of the previously loaded' error-messages suggest that somehow you have duplicates of those extensions installed in different locations, both of which SketchUp loads from.
Several of those causing errors are by other authors and are from other sources than SCF, and even some su_ shipped-extensions...

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...

Good day, I made a donation back in 2018. Can't remember if Fredo had paid plugins back then. I have recently updated my LibFredo6 and my round corner plugin no longer works, and is telling me that my trial version for LibFredo6 is expired. I am still on Sketchup version 2018. Please confirm I need to purchase round corners again.

You have no license registered for any of my plugins, at least under the username Slimdog.

So, you need to purchase one.

@fredo6 Thanks for the response. I just had to install sketchucation tools and it works now.

Hi- I've been using Libfredo tools for a while but recently had a hardware issue with one of my drives unrelated to the SU install or the additional folders location. Basically SU graaaaduaalllyy froze along with my PC and I had to force a hardware shut down. On replacing the hardware and starting up SU again, I'm getting errors pop up- "You must install Libfredo6 or above"; I have manually reinstalled this via SU from the additional folders location but it didn't work on reopening of SU with the same message. This is the followed by load errors of the extensions including libfredo etc.

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

fredo6

It would be helpful that you indicate which version of SU you reinstalled, and which of my plugin you were also trying to install.

Also, please quote the error message correctly.

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

Hi- manged to delete the original post so restated with additional info requested (!) I've been using Libfredo tools for a while but recently had a hardware issue with one of my drives unrelated to the SU 2023 (on win 11) install or the additional folders location.

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.

Tpdart

All working now- thanks
