I'm trying to create a Python toolbox (pyt), but it fails (via the contextmenu). I'm getting the error "failed to create the toolbox file", although a pyt-file has been created (with no syntax errors). Also a correct Python-toolbox with a tool (created on an other machine) doesn't seem to be interpreted right on my machine (red cross in icon).
Seems like something with the XML's. The xml's aren't created...
I'm running: VirtualBox with Win7 64bit, ArcGIS for Desktop 10.1 SP1
