64/32-bit runtime enviroment option during installation, which one?

Hi,
I just installed Tumbleweed and by clicking on the software list title during installation I was presented with various options… all very clear except one:
32-bit runtime environment and 64-bit runtime environment.
Both where unselected by default: is that normal?
Obviously my CPU is a 64bit one so I selected the 64-bit option, is that all right or should I have left them both unselected as suggest by the default installation?

Thanks

anyone? :slight_smile: thx

if you don’t understand what they are leave those check boxes alone, yast will install what runtime it needs, and if and when you install a 32bit application (like skype) yast or zypper will install the needed runtime, personaly I have never wasted time with that option as yast and zypper are great in installing needed dependencies.
