The error messages are in English. You may be able to understand some parts of it, for example

Most extensions allow to apply a license after starting SketchUp. If that is not the case with Skalp, maybe it has a separate installer executable?

  • Try uninstalling and reinstalling Skalp.
  • Since Skalp is a commercial extensio and you are a customer, you certainly get professional support be the Skalp authors. Try to contact them.
