I can't stop ExtrudeAlongPath being 'mine' - as I wrote it.
However, if you want to fix it then you have my permission to edit it.
Note that it is so old it does not comply with any of the current good coding principles, and even uses some unacceptable $xxx global variables...
That's why it was superseded...
And please note that criticizing my newer Extrude Toolset scores you no plus points at all !
I just tested PipeAlongPath and it works fine in 2024 - what's your issue...
Do you have the newest v2.2 - but it is 10 years old !
ExtrudeAlongPath - what is that ? It's not part of the current Extrude Toolset and it's not in the PluginStore...
Here's v2.0 in the PluginStore...
https://sketchucation.com/pluginstore?pln=Re_Glue
It now allows multiple pre selected component-instances, but still only one preselected face.
These are glued to the face [is possible], any errors or unsuitable instances are reported in the Ruby Console...
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...
Rather than prolong this...
Here's the updated v2.0 of the RB, which now meets modern standards etc, and works in v2024 [and earlier]
ExtrudeAlongPath.rb
You need to install the latest versions of the extension, LibFredo6 and the SketchUcation toolset [for the licensing].
That error message says the signature-file cannot be read.
You may have changed your computer's name, which invalidates it.
It suggests you open the signature-file's folder and delete it.
After a restart a new signature file is made to suit the current setup.
The validate your license[s]...
Note that errors like this can also occur if your computer's name contains non-ASCII characters - going against the advise of Windows.
I suspect that you are Chinese - so have you got any special-characters in your computer-name ?
This can break licensing setups like this...
Try renaming your computer following these rules...
A-Za-z0-9 - are OK
The following are not OK...
period (.)
backslash (\)
forward slash (/)
colon (:)
asterisk (*)
question mark (?)
quotation mark (")
less than sign (<)
greater than sign (>)
vertical bar (|)
And ay other special characters or non-ASCII foreign alphabet letters will also cause issues,
@Fer18
Your posts makes little sense !
If you need LibFredo6 download/install it from the PluginStore.
If you need some other Plugin [aka an Extension] then post in its thread - OR explain yourself better - we are not mind-readers...
Get the latest version from the SketchUcation PluginStore
http://sketchucation.com/resources/pluginstore?pln=2Dtools
or why not use the AutoInstall feature of the 'SketchUcation Plugin Store' toolset's dialog...
Only on a flat Z-plane - these are 2D Tools... 
Although some like Fillet work in '3D' too...
