How did you attempt to install TIG-Weld? Did you just put the downloaded RBZ file into Plugins?

Yes

So as you can see from TIG's remarks, you didn't actually install TIG-Weld at all.

OK - so I tried the window > preferences > extensions > install extensions button and navigated to the download folder. I picked TIG-weld.RBZ and sure enough it installed. I did the same for the cut-face extension (and all this time I was wondering why it didn't show up in SketchUp) as well as for for TT_lib. Not sure what the latter does though.
Anyway, I TIG-welded a couple paths but they still did not extrude.

I demonstrated that ALL of the 'problem paths' you supplied can be made to extrude with PipeAlongPath.

You need to select one full path [double-click part of it so it all selects], then use the right-click context-menu.
If 'Explode Curve' appears, then choose it, some oddly made curves seem to be causing issues.
but it it's not there there might still be some issues with short or reversed edges etc, so do this next step in all cases...
With those edges [re]selected use TIG-Weld to combine them all into one bound curve.
Now reselect that curve and use PipeAlongPath on that.

Following these steps I have not had a single failure with your 'problem paths'...

OK
Thanks!
