Your Firewall has a list of sites it prevents access to - a 'blacklist'.
There is a 'whitelist' of sites that are allowed.
Manage your Firewall and add *.sketchucation.com to that...

Have you restarted SketchUp to sync everything ?

Have you installed the SketchUcation Tools needed for licensing ?

Assuming you are using Windows - have you installed Sketchup properly ?
Double-clicking the installer's exe file to 'Run' it is not enough, even if your user account has admin powers - doing so can cause unpredictable issues, often around permissions and file access.
It can be repaired without needing to re-install SketchUp - do the following...
It will leave any installed files etc unaffected...
Close SketchUp.
Find its installer exe file - usually in your Downloads folder [down load a new copy if you no longer have it].
Select the exe file's icon, right-click > context-menu > Run as administrator
When prompted choose Repair.
When it finishes restart SketchUp.

Any improvement ?

@rutpin
So you installed the FredoScale extension.
I assume you installed it from an RBZ you've downloaded, using the Extension Manager > Install method...
When it's installed it doesn't appear in the 'normal menu list' - by which is must assume you mean 'Extensions', it's under the 'Tools' menu, and also has a Toolbar which you could activate.
I don't understand your 'where do you open the icons' ?? Please explain...

You will also need LibFredo6 [for the helper methods] and the SketchUcation Tools [for the licensing] installing...

Restart SketchUp after the installations to sync everything.

After that it doesn't appear, or it is not at least listed in the Extension Manager dialog, then come back for more help...

@rutpin
This is not enough information.
What 'plugin' ?
In which menu is it meant to appear ?

@f6eao
Support needs to check on this.
Have you checked your email spam-folder, as used in relation to the address used to gain a membership ?

If you login to our website and go to the My Licenses page is it listed ?
https://sketchucation.com/webshop/my-licences.php
If so, then you should be able to download it from there...

@rutpin
After you downloaded the RBZ did you install it from the Extension Manager dialog ?
Or are you using the SketchUcation Tools' ExtensionStore³ to auto-install it without an RBZ ?
Do you have the latest LibFredo6 installed as well ?
Do you also have the SketchUcation Tools installed [needed for any licensing] ?
Have you restarted SketchUp after the installations to sync everything ??

@Eric5261
File.exists? AND File.exist? methods have worked forever. although the File.exists? method has been deprecated for along time, but someone decided to remove it completely from the Ruby version used by v2024.
This has caused a lot of problems with code - I myself have had several files to fix for full compatibility.
To an English speaker File.exists? is the more logical grammatically correct form, so why it changed is somewhat mysterious.
It's a simple matter for the author to edit the files so only File.exist? is used...
If the file is RB you could edit it to suit, but I'm sure that Anton will fix it asap...

@Finito86
The error message is useful.
It appears that several extensions are failing to load beyond their initial RB file which sets them up, by running another file - often an RBE in its subfolder - that loads all of the stuff necessary for making the menu items, toolbars and running the code.

Your errors include the DC and sandBox extensions which ship with SketchUp and get copied into your Plugins folder before it runs and then loads extensions...
It's also failing to load the LibFredo6 and SketchUcation stuff, and Trimble Connect.

This suggests a permissions problem in that the files are unreadable.
Let's try with just one issue... SketchUcation
Check in your Plugins folder that SketchUcation.rb and the SketchUcation subfolder exist.
Now in SketchUp open the Ruby Console - Extensions > Developers menu
Type in the bottom section:
load 'SketchUcation.rb'
See what happens - you might get errors similar to what you've posted.
If not then check the Extensions menu for a 'SketchUcation' submenu...
Is so then try typing this:
Sketchup::require('SketchUcation/SCF_loader.rbe')
Does anything happen ?
If not then SketchUp isn't managing to load files it needs...
Close SketchUp.
Try finding your Plugins folder icon in
C:/Users/Finito/AppData/Roaming/SketchUp/SketchUp 2022/
It's a hidden file but the full path in a Windows Explorer window should open it.
Or choose the Folder Option to show hidden files...
With the Plugins folder icon selected right-click > context-menu > Properties > Security and pick 'Edit...'
Select each of the Groups or user names in turn and ensure that the box for 'Full control' is ticked.
The changes should trickle down to all enclosed files and subfolders etc.
Once it's done OK the dialog and try restarting SketchUp.
Any improvements now... ??

@Finito86
All of your extensions listed seem to be the newest versions, they are also activated.
So this suggests there's something very wrong with your SketchUp installation than is not creating menu items and Toolbars for them...

Can you try the following... it will not affect anything you've customized or installed etc.
Close SketchUp.
Find its installer exe file - usually in your Downloads folder [if necessary download a new copy]
Select the exe file's icon, right-click > context-menu > Run as administrator...
When prompted choose 'Repair'.
When it's finished, restart SketchUp.
See if it's improved things...

Running an installer's exe file by double-clicking on it is not the same, even if your user-account has admin powers.
This can cause all kinds of unexpected issues - yours might be an example.

@Finito86

Your Extension Manager ['Administrador de extensiones'] dialog - you have shown us it with the 'Gestionar' [Manage] tab selected in the top bar.
All of your active extensions seem to have 'Desinstalar' [Uninstall] in bold.
'Actualizar' [Update] is in feint.

You have not shown us the 'Inicio' [Home] tab.
The entries under the heading 'Habilitar/Deshabilitar' (or 'Activar/Desactivar' ?) [Enable/Disable] should all read 'Activado' [Enabled] - because if they read 'Desactivado' [Disabled] then those extensions won't load, their menu items and toolbars are not then shown etc...
Can you check that ?
You need to restart SketchUp after making such changes...

@ntxdave
The current version of SketchUcation Tools works on versions >= v2017
If you have bundles relating to other versions [newer or older], then you should be able to use them in v2020...

@mbarker
I've replied to you in a PM

I just tried it on v2024 and it works fine... although most of it is over a decade old !
It imports a text file with a camera-view on each line.

The camera-view entry must be as follows...
name,xeye,yeye,zeye,xtarget,ytarget,ztarget,rollangle,fovangle
there can be an optional value added after 'fovangle':
,image
But you probably aren't wanting to use that.

The values in the entry must be separated with the constants that are set in the RB file:
Edit the ICVSEP and ICDSEP constants to suit your typical file's locale value-separator [' ',;:\t] and decimal.separator [. or ,]...
In the example I show it's as a comma , separator and a .
You might use a space or ; and a , to suit locale.
Please check you are setting up you file correctly.

As I said it works fine given the correct input.
To attach an RB file just drop it into the message
TIGimportcamera.rb

There are donation buttons against many authors entries in the PluginStore and ExtensionStore³

@Finito86
So...
SketchUcation seems to be properly installed into your Plugins folder, you have previously show a screenshot showing it's enabled in the Extensions Manager.
You have not expanded its entry in that dialog to show the installed version - which should be v4.4.1
The same comment applies for LibFredo6...

Is there a submenu entry in the Extensions menu for SketchUcation ? Can you open a dialog for the ExtensionStore³ from that ? Can you activate its Toolbar ?

As Fredo explains his Lib is an 'enabler' toolset, and does nothing on its won, unless you install one or more of his extensions that will then use its features as needed...
Because many of Fredo's extensions also need a license, then the SketchUcation toolset is also needed to provide that functionality.
As previously explained the ExtensionStore³ dialog also lets you AutoInstall directly, without having to download an RBZ first...

@Finito86
You say you have 'installed' these extensions...
But you published a screenshot showing the downloaded RBZ files for these extensions, not the installed extensions themselves.
You need to actually install an RBZ file's contents into your Plugins folder.
Use the Extensions > Extensions Manager dialog to Install... them [but see below for an even easier way...]
Restart SketchUp to sync everything after the installation[s].
Most of Fredo's extensions will also require his LibFredo6 installing as that provides many 'behind-the-scenes' functions...
Note that you will need the latest SketchUcationTools installing, to run for any licensing...
But, if you install the SketchUcationTools there are several very helpful additional tools created in SketchUp - e.g. the ExtensionStore - a dialog which let's you AutoInstall extensions directly from our PluginStore, sidestepping the RBZ part download altogether.

@adams_1127

Please explain what you mean.

LibFredo6 does not 'work' at all - it simply adds functions that are used by many other Fredo6 extensions.
If you have the latest versions of the LibFredo6, the related Fredo6 extensions and the SketchUcation Tools [for the licensing] installed - and SketchUp is restarted so that everything is synced, then things should work...

If you are having specific issues, then please explain them clearly, so that Fredo can help...

@a4jp-com

As I said in my last post... It works with v2024 - I tested it.
You just need to have a WorkPlane made to project on to [my separate Plugin], and because very old plugins like these are unsigned, then your Extensions Manager's Loading Policy needs to be set to Unrestricted.

You asked in your previous post for it to be 'updated' - how?
It's very old and won't be changed now - but it still works...

@junphuc17945
Can't you login and manage your licenses yourself ?
https://sketchucation.com/webshop/my-licences.php

@a4jp-com

It's a very old plugin - ~14yrs

What's your issue ?
What update might you consider appropriate after 14 years... ??

I just tried, and as long as you have both it and my required WorkPlane plugin installed, and you follow the instructions, then it works OK.
These plugins are so old they as you might expect they are not "signed", but with an Unrestricted extension-loading policy set it's all OK...

@lucarcari
Having changed computer has probably messed things up.

Assuming you no longer have access to the license file you saved onto your previous computer, or the email which sent it to you, have you tried the SketchUcation My Licenses page, whilst logged in as the user who bought the license ?
https://sketchucation.com/webshop/my-licences.php
This allows you to deactivate any 'old' licenses, download a copy so you can activate a new one etc...

@PROYECTARIUM

When you buy a Fredo6 license it allows you to install it [and validate it] on up to 3 different computers.
You simply copy the license file onto the other computer and use that file to activate a license for the related extension on that computer.
There are also tools available on the SketchUcation website to manage licenses later on - e.g. if you get a different computer that needs a license, and you can remove a validation from the previous computer.

Cuando compras una licencia de Fredo6, te permite instalarla [y validarla] en hasta 3 computadoras diferentes.
Simplemente copie el archivo de licencia en la otra computadora y use ese archivo para activar una licencia para la extensión relacionada en esa computadora.
También hay herramientas disponibles en el sitio web de SketchUcation para gestionar licencias más adelante, p. si obtiene una computadora diferente que necesita una licencia, puede eliminar una validación de la computadora anterior.
