Extension License Missing in my sketch up 2024

I download different plugging to try to minimize the weight of my objects (polygons quantity). The downloading is ok but then when I try to use the tools a pop up appear and it’s says that they can’t find my licence. Can someone help me with that? I’ve try different plugging, they are not the problem. I’ve try to close and restart Sketch Up, didnt work either.

sure. what plugin is it?

I’ve tried a couple. The last one I didnt uninstalled yet is Skimp.

Read the fine print: Free download but you must order a free trial or paid commercial license from the Skimp website:

I’m asking because extensions have various ways of dealing with their licences. skimp does it one way, fredo’s do it another way, then eneroth’s as well…

in skimp’s case, it’s a demo yeah.

Oh ok thank you
