Good day.
I hope this will give you information for the initial release.
I am not expecting an answer or help.
This is just FYI.
I downloaded
https://github.com/roundcube/roundcubemail/releases/download/1.6-rc/roundcubemail-1.6-rc-complete.tar.gzExtracted it to wwwroot
so its path is C:\inetpub\wwwroot\roundcubemail-1.6-rc
When I try to browse to
http://my domain/roundcubemail-1.6-rc/installer/
I get these error messages:
