First oft all i know that Linux is not supported. This question is only for my own fun and it is no problem if it chould not be fixed.
I am able to run Rhino5 on Linux using wine so now i like to run v6. Saddly the installer is chashing by installing the Visual C++ Redistributable Packages.
In rhinov5 i could install this packages with winetricks and your v5installer isnt trying to install them again. Not in Rhinov6. Your installer is downloading them and trying to install the packages regardless they are allready installed.
Is there a way to skip the check/installation of all vcrun packages?
