@D_C_E I’m sorry I didn’t see this post; it does not show up in the forum index for reasons that are unclear to me. If you’re still having trouble, please contact tech support directly — we’ll get you taken care of.
@pythonpinky This is an unrelated issue. The issue is that the software requires python 3, and you are (somehow) running Python 2 here. (The Inkscape extensions no longer work under python 2.) Please update to python 3. Make sure that you’re running Inkscape 1.0 (or newer). You may also need to manually edit Inkscape’s preferences.xml file to explicitly state which version of python to use, if it’s still locating python 2.
