FYI: The latest installation of rhino_de-de_7.0.18254.04325.exe changed my Rhino 6.9 installation. The languages (German, English) were gone in the Rhino 6.9 options, and I was not able to repair the Rhino 6.9 installation. I’ve got this Bootstrapper.exe request dead end.
After a deinstallation and reinstallation of Rhino 6.8 it runs again. Argh.
