The following extensions of mine have been updated for compatibility with v2024 Ruby - the deprecated Fixnum has been removed.
https://sketchucation.com/pluginstore?pln=ExtrudeTools - v6.0
https://sketchucation.com/pluginstore?pln=Latticeizer - v1.9
https://sketchucation.com/pluginstore?pln=Roof - v6.0
https://sketchucation.com/pluginstore?pln=SKMtools - v20240425
https://sketchucation.com/pluginstore?pln=TIG_Smart_offset - v4.0

v5.0 of PurgeAll is available - it fixes some minor glitches with v2024 changes...

The reason the toolbar appears is, because there are updates available - hence the red marker on the first button - not present otherwise.
If you open the ExtensionStore dialog and choose to install the updates, then close the toolbar, when you restart SketchUp the toolbar stays off, until you next activate it.
If you don't want the updates simply dock the toolbar in the side bar with others, it's unobtrusive...

The method File.exists? has long been deprecated, but worked.
In the latest Ruby version it doesn’t - File.exist? - works in v2024 and older versions as well.
Many developers are working to adjust their code accordingly.

Have patience and post any instances in an affected extension's thread - as there are 100s of 1000s of line of code with the tiniest corrections needing to be found and change, then the extension re-encrypted and signed…

Many authors have already fixed their extensions, so look regularly to see if there’s already an update available…

@Joel3dm
Yes.
Make the non-auto-updating SectionCutFace unLocked and choose a material/color that's already used in the model [from a list].
A SCF's material applies to all faces, but you can edit the group and apply any material to any face etc...

Use the Outliner.
You can then expanded the 'tree' and select the nested Container, and double-click it in the Outliner to edit it that way.

The SKP you provided has 2 roof faces at z>0 [faces at z0 don't work].
These 2 are identical in edge sizes and orientations/direction.
The one on the right takes a hipped roof OK, but the one on the left fails with an error message.
This is weird.
However, if you follow the advice in the error message on that problem face. and erase one edge and remake t the new face will also take a hipped roof OK.
Something in your model's database is skewed.
But it is fixable...

Why not email support at sketchucation.com - they can advise on acceptable payment methods...

@Gábor
The issue is more widespread than this.
If you have a v2023 file and attempt to load a SKP component that's v2024 it will fail 'silently'.
Also trying to open a v2024 SKP from within v2023 also fails the same way.
If you manually open a v2024 using v2023 an message pops up about it being from a newer version, but you can skip and continue...

So any code which takes an exported v2023 component, manipulates it via the C SDK and returns it as a v2024 file is doomed to fail as explained above...

Perhaps the only way is to spot the version of the 'parent' SKP and its exported component, and use a suitable C SDK file to process it back into the compatible v2024 format ?

For backwards compatibility it'll need to cover v2023, v2022, v2021 and v2020 files because the 'versionless' v2024 format breaks those [perhaps using v2020 format for all exports would work in all newer versions ?] - more testing with any upcoming v2025 might reveal further issues...

@unknownuser said:

I can't validate the round corner license, in the extension box the error says communication failed with sketchucation

See the previous reply about why this might happen...
And how to fix it...

@bebert77
Please give us more info.
Error messages / dialogs etc...

@alskaro
You can already do that to a section cut face group.
Unlock it [if needed], then edit the group, and apply the different materials you want to the faces.
If you regenerate the section cut face then those changes are lost.

@Jspro
If you read the extension's 'more info' link in the PluginStore you will see it works as far back as v8 !
So the answer is yes.

I think not.
Try out some permutations and see what's best for you...

Find your version's Plugins folder.
Open it.
Extract the contents of the RBZ [ZIP] for the extension/plugin.
The resultant folder should contain a .RB file, and possibly a subfolder of the same name.
Copy the .RB file and subfolder into your Plugins folder.
Restart SketchUp to load the .RB file... follow the instructions on the extension's usage...

Use the Outliner.
You can then expanded the 'tree' and select the nested Container, and double-click it in the Outliner to edit it that way.

It's not published, buy you could try contacting its author and offer to buy it ?
See the first post in the thread...

So at the moment you have SketchUcation toolset v5.0.3 OK, the SCF licensing OK and most of Fredo's extensions OK.
BUT Fredo'sTools must be disabled for this to get everything else working.
So the issue lies with FredoTools.
Have you tried reinstalling FredoTools from a newly downloaded RBZ ?

@slbaumgartner

I meant the SUp version.
I suspect that most users will have newer SUp versions ?
The reason I cited @fredo6 is that he is instrumental in the licensing coding, and I am inviting his input...

The licensing code hasn't changed in several versions but that seems to now be causing at issue - way back to the lat v4 ?? @fredo6 ??
Other MAC users haven't reported anything... Are you still running v2019
