Does King of Stars work with Windows 10 and is there a bilingual version available?
No, the application doesn't work on Windows 10. I have tested on both 32 and 64bit versions of Windows 10 and it doesn't work at all. It's impossible to say when there will be a version compatible with Windows 10. I have also tried to apply a compatibility tweak without success.
I recommend you report this issue to the developers using the following form: http://www.delemme.com/contact-us.html
