@sashapepperspray
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…

@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...

@grizzler When you [re]installed SketchUp/Layout did you do it properly.
If not then you can repair it without affecting anything you've got set up.
Close SketchUp/Layout.
Find the SketchUp installer's exe file - usually in your Downloads folder.
Select the exe file's icon, right-click > context-menu > "Run as administrator"
When prompted choose "Repair".
When it completes restart your computer and see is SketchUp/Layout now works as you expect...
Running a complex app's installer's exe file by double-clicking it to 'Run' it is not the same thing, even if you have admin powers.

@grizzler

You should go to the PluginStore and update to the SketchUcation toolset v4.4.0 which has been specially reworked for v2024 compatibility. If deals with the SCF licensing for many extensions.
If you use any of Fredo's extensions, he has also updated them all for v2024 use and don't forget his latest LibFredo too...
After installing these restart SketchUp to sync everything...

@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...

@Rich-O-Brien

Liam, get as well as you can soon...

Reminded me of this dickwad

Thomas Midgley Jr. has been named a “one-man environmental disaster” for two big reasons. He was one of the early pioneers of chlorofluorocarbons (CFCs) – compounds that became widely used in industry – and which were destroying the ozone layer. He also invented leaded gasoline and insisted that it was safe to use.

Perhaps there is a god, because after that he got polio and was partially paralyzed, he invented a pulley contraction on his bed to move him, but one day he became entangled in it and was strangled !

As Rich says, switch off Length Snapping - it is more trouble than it's worth !
It offers no advantages.

@luciofra

Many of Fredo's extensions now require licenses, as do some other authors' work.

These perpetual licenses are relatively inexpensive [typically $7 to $15 each].
There might also be discounted 'bundle' licenses available, e.g. Fredo's bundle contains 8 of his most popular ones.
https://sketchucation.com/purchase.php?plugin=Fredo6Bundle2022
and costs $40/$24 for premium members.

Premium members get considerable % discounts.

You also need to install his help LibeFredo6 [free]
licensed extensions also require the SketchUcation Tools [free] installing which sets up the licensing side of things.

This page covers all current licensed SCF extensions...
https://sketchucation.com/plugin-list.php

This is the general licensing guide...

And this page lets you manage your own licenses...

@SilentFart

But you haven't mentioned the next step where I gave you the exact menu-path to it...
Tools > Fredo6 Collection submenu, as 'ThruPaint'....

@SilentFart

You need to restart SketchUp after it's installed to sync everything.
After that it's listed under the menu 'Tool's > 'Fredo6 Collection' submenu, as 'ThruPaint'....

@FairhavenMatt

Also remember that working on any program's files that reside away from your computer also risks losing data when saving - which is irretrievable.
Always work on a version of the file on your computer, saving it there as you work.
When that work is completed save a copy of the file over onto the 'remote' location.
Having your version on your computer is no harm and a useful safety net if you get problems with the remote copy getting made.
Making a remote copy of a file is far less likely to cause any issues, as the OS is very robust at doing this, whereas any ap saving remotely is more likely to have hiccups...
In your case the remote location is not accessible, but if it had been you have the ever present risk of a glitch in the file's data - potentially making it unusable...

@Prorab

It says you already have three seats allocated to computers using those licenses., so there are none free
If you have changed the name of a computer, then that counts twice etc.
You can log in and manage your licenses using
https://sketchucation.com/webshop/my-licences.php
Remove what's not needed and then validate again...
Also ensure you have the latest versions of the extensions, LibFredo6 and the SketchUcation toolset [for licensing] installed and SketchUp restarted to sync everything...

@ZG53
If you read all of the thread and the guidance notes...
The JAR files that ImageTrimmer uses must run/open in Java.
So firstly you need to have Java installed [if you don't already have it, the it's freely available off the www...].
Next you must ensure that the JAR files are set to open with Java, many unZIP/decompression tools like WinRar hijack that file type and open it themselves [uselessly]. Go into the associated filetypes in WinRar and untick .JAR...
ImageTrimmer should now run as intended, although to do need to ensure it's working on a PNG file Image with fully solid and transparent areas...

@Yarun

It's a Firewall setting in your computer's security settings [or Network security settings, or your AntiVirus tool settings]
*sketchucation.com* should be set in the whitelisting...

@Mike-Amos

Did you install SketchUp 2024 in the approved way ?
You can repair it either way...
Close v2024.
Find the v2024 installer's exe file [usually in your Downloads folder]
Select its icon, right-click > context-menu > Run as administrator...
When prompted choose 'Repair'.
When it completes restart SketchUp.
Any better ?

@Mike-Amos

Are things shown as 'installed' in the native Extensions Manager dialog ?
Is the SketchUcation Toolbar listed as an available toolbar ?
Have you tried activating it ?
Is SketchUcation listed under the Extensions menu - you can activate it from there too ?
or... are you saying something else ?
Are you saying that the Plugins [Fredo's?] aren't listed in the Tools menu items ?
Do you have the latest version of LibFredo6 installed ?
Have you restarted to sync everything after the installations ?
Have you downloaded the appropriate licenses
Have you validated those licenses for each extension ?

More info please...

@natas_ha

Which of Fredo's extensions did you license ?
Do you have the latest version of his helper extension LibFredo6 installed ?
Did you restart to sync everything ?
Also do you also have the latest version of the SketchUcation tools installed - for the licensing...

If none of this helps repost and someone will ask you for more details...

@IsaiARQJ
LibFredo6 is a free library used by many of his extensions - some of those are paid.
So you do need alicense for that library.

LibFredo6 es una colección gratuita que utilizan muchas de sus extensiones; algunas de ellas son de pago.
Por lo tanto, necesitas una licencia para esa biblioteca.
