Why isn't check for updates working?
If attempting to check for updates gives the error "Can't download file: A connection with the server could not be established" it may be a TLS version issue. In Control Panel / Internet Options, Advanced tab, under Security, find the options "Use TLS 1.1" and "Use TLS 1.2" and make sure they're both checked. In Windows 7, only TLS 1.0 is checked by default.
