Wait I figured out, installing it portably (from MS Store) will work

Okay, It seems to be an CloudFront issue maybe @hazelnut

Tried every step but doesn't work @nukecad

It only affects for my PC.

Also, I forgot to say that I don't have CCleaner on my computer. Nope, only CCleaner website is unavailable.

This appears when I go to WWW.CCleaner.Com: Chrome on Windows This site can’t be reached Check if there is a typo in www.ccleaner.com. If spelling is correct, try running Windows Network Diagnostics. DNS_PROBE_FINISHED_NXDOMAIN
