Trying to install Rhino 5
OS Windows 7 Pro 64
Installer message "Windows … or 7 required, upgrade your OS
Please help

Hi Altan,

Are you running Windows on a PC or a bootcamp partition on a Mac and is it up to date with important updates from Microsoft?

Hi Brian
First message was 1603, details something related with registry
Second attempt, the installer unable to detect the OS

Action center message:
Windows update does not require any action
