Toposhaper fails installing on SketchUp 2026

[Epix3D]

I have a licensed Toposhaper plugIn but when I try to install on SU 2026 I get the message
Failed to install?

Anybody know how to solve this?

[Dave R]

How did you try to install it?

[TIG]

If it is licensed you must already have the SketchUcation toolset installed to cover the licensing.
Use the SketchUcation toolset's ExtensionStore dialog to first check that you have the latest toolset version installed - if not then install it and restart Sketchup.
After that use the ExtensionStore dialog to Auto-Install the latest LibFredo6 extension, and restart SketchUp
After that use the ExtensionStore dialog to Auto-Install the latest version of Toposhaper, and then restart SketchUp.
Any improvement ?

I used your method step by step TIG -still cannot find Toposhaper though the install says success. I did turn on and off SU for each step.

You need to read its usage instructions AND also install LibFredo6 [as well as SketchUcation tools] which contains supporting code.
Most of Fredo's extensions appear under the Tools menu, Fredo6 Collection > TopoShaper - It also has a Toolbar which you can activate...

Sorry,- but still not showing up...

This is a very strange issue...
You haven't explicitly said it but I assume you've installed the other two extensions that I listed.
If you download a brand new copy of TopoShaper RBZ from our PluginStore and manually install it with the Extension-Manager do you still get the installation error message ?

I just installed it and it's fine, BUT I did notice its reported as 'unsigned' after the install. so perhaps @fredo6 needs to fix that.
Also, if your Extension-Manager Loading-Policy is set to anything other than 'Unrestricted' then that might be causing issues ?

@TIG
This is strange that the rbz is unsigned. Is that the only one of my plugins?
I can re-release it to see if this changes anything.

[TIG]

@fredo6
Everything else seems signed OK.
So something seems to have gone wrong with the TopoShaper RBZ ?
But for me it load OK when 'Unrestricted' so it's not faulty - just something have changed within it to mess with the checksum ??

[fredo6]

Ok. I will republish it....
