Hi Georgy -
Thanks for reporting that, I’ll have someone check the broken links.
I’m not very familiar with language packs but are you sure that English isn’t available from
Rhino Options > Appearance > Language used for display?
Or, in German:
Rhino-Optionen > Erscheinung > Für die Anzeige verwendete Sprache
If not, you should be able to download Rhino 5 in English from this page:
Provide you eMail address and click Next. On the next page, click Download English Now and install that version.
When you then install that version, it should add English to the options.
Does that help?
