This is puzzling, the minimum system requirement for C11 is apparently Windows 8.1 which I’m gladly running on my machine.
However, whilst trying to install the C11 it stops telling me that my system does not meet minimum requirements.
Is this a matter for the Customer Service or am I missing something?
Windows 8.1 had end of support two years ago (January 2018)
Running unpatched systems means that your computer becomes a host for malware that targets other systems on the internet.
E g, it might not be a problem for you (until and unless you get ransom-wared) but you’re creating a risk for everyone else!
