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.

@katsia
Your post doesn't explain everything exactly.
Why did you disable anything ?
An installation of a newer version is sufficient.
To use this tool you need the latest version of it installed - you say you've done that...
You also need the latest version of the SketchUcation toolset installed for any licensing - you say you have done that...
You must also have the latest version of LibFredo6 installed - you have not confirm doing that.

After installing these files you must restart SketchUp to sync everything.

If you have done that, then what appears in the Extensions Manager dialog ?
What appears in the Tools menu submenus, and Toolbars for that extension ?

@Mike-Backman
Have you bought a license for it ?

If you set z_min and z_max to the correct points it'll work.
Currently you are specifying them wrongly,
to the bb's 0 corner [z min] and 4 corner [z max]
Instead do something like this to set them to the y_max point
z_min: bounding_box.corner(3).transform(transformation.inverse)
and the corner point above it
z_max: bounding_box.corner(7).transform(transformation.inverse)

All of the 3 seats are allocated, presumably using your old computer[s] details.
You need to free up the seats so that you can reactivate them for your new computer[s].
If you have the latest versions of the extension and the SketchUcation toolset [for the licensing] installed, and SketchUp restarted to sync, you should be able to do this using the submenu items for the extension under the Tools menu.
You can also manage each of your licenses by logging in to SketchUcation.com and using the menu item PluginStore > My Licenses... page...

3개의 자리는 모두 할당되었으며, 아마도 이전 컴퓨터의 세부 정보를 사용하고 있을 것입니다.
새 컴퓨터에서 다시 활성화할 수 있도록 자리를 비워야 합니다.
최신 버전의 확장 프로그램과 SketchUcation 도구 세트[라이선스용]가 설치되어 있고 SketchUp을 다시 시작하여 동기화한 경우 도구 메뉴 아래에 있는 확장 프로그램의 하위 메뉴 항목을 사용하여 이 작업을 수행할 수 있습니다.
SketchUcation.com에 로그인하여 메뉴 항목 PluginStore > 내 라이선스... 페이지를 사용하여 각 라이선스를 관리할 수도 있습니다.

@chiklopes
That error says you are trying to us a license file for another plugin [extension].
This can occur if, for example, you have a license for RoundCorner and you try to use it for FredoCorner - these are two different extensions and need their own licenses...

Please give more details if this isn't the case.

PushPull should work.
But you must edit the 'container' so you are working on its geometry...
BUT I do see the problem with PushPull.
One of the notches you've made near the end isn't perpendicular to the long rear face, so you can't push into it.

A minor adjustment to the geometry fixes it so that Pushpull works...

I copied the similar face across and edited the skewed geometry...

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

@Alohaa
There are several ways to do this...

1. Edit the 'container' [group or component] and select the rear face.
   Use the Move tool and constrain the movement axially, type 5mm
   The 50mm becomes 45mm.

2. Edit the 'container'.
   Draw a guide line 5mm off the back face [on the end part].
   Then select the rear face and use the Move tool, snapping on the face and then the guide to relocate it by 5mm.

3. As in 2. above, but PushPull the relocate the rear face by 5mm.

4. Edit the 'container' and use PushPull on the back face to move it over, type in 5mm.

Note that editing the container and then using the Scale tool on the geometry, with 45mm typed in could work, but because you have a 'notch' in it, it will then be distorted by the scaling...
So Scale is best used for simpler forms...

@FlorinAp
That code has never worked.
The code as presented applies to a Class [XLinemTool] which should be inside a Module.
No Class is defined.
There's no RB file to set up the extension as SketchUp loads, and the image PNGs are not in a folder with the main code.
There's also three trailing ` characters.

If the missing parts were supplied and the whole lot then packaged in an RBZ file, life would be much easier for every one...

@FlorinAp
Don't manipulate the selection directly.
Instead make it an array first...
This will guard against crashes somewhat...

selection_to_change = selection.to_a

@FlorinAp

Now I understand better.

My main point was that if there are instances of the same component in different contexts they get added to the selection and manipulating a selection spanning contexts can lead to crashes...

@FlorinAp
Sorry, but you are not explaining this at all well.

Select All = what ? - e.g. All Groups in the model
Select Active = what ? - e.g. Groups in the active context
Select Active... ? - e.g. Groups in the active context, with the same tag/layer
Select All... ? - e.g. All Groups in the model, with the same tag/layer

What do you do with the selection etc ?
Changing a selection of entities across will cause crashes etc...

The menus and naming are secondary - we need clarity on what it is you hope to achieve.

@FlorinAp
That code leaves a lot to be desired,
Please explain how you want to use the code to select and change groups by matches or layer etc...
I think it's much easier than you expect...

@FlorinAp
Doesn't Dezmo's code do this ?

@Jerome_971
But v2017 does use the built-in Chrome browser with any HtmlDialogs [like the ExtensionStore's]

@jskwonb
Have you tried following the advice in the error-message ?
Have you installed the latest versions of the extension, LibFredo6 and the SketchUcation tools [for the licensing], and restarted Sketchup to sync every thing ?
Also, this kind of error relating to reading a license file often occurs if your computer has not been named following Microsoft's conventions - e.g. its name should contain only ASCII letters and numbers, and a few other common punctuation characters; it should not contain special characters [I note your image's name contains some Asian characters]. You could try renaming your computer ?? Also your PC's user-name has similar restrictions...

@Adept-Design
Have you installed the newest versions of Fredo's extensions and LibFredo6, and the SketchUcation toolset [for the licensing] ?
Install extensions using the SketchUcation ExtensionStore³ system or download the RBZs from our PluginStore and use the native installer, through the Extensions Manager...
Restart SketchUp after the installations to sync everything.
There should be submenus under Tools for Fredo's extensions, including license activation etc.
There are also menu items and Toolbars to use these tools etc...

@Jerome_971
@Rich-O-Brien or @Gabor will get back to you with detailed advice.
I think this has been reported a few times before and resolved...

IE11 is not needed with newer dialogs which use a built-in Chrome browser system
