Can't open the Zwift software in my PC

How long as it been updating for? Mine seemed to take forever! And i have very fast internet, even on my main computer, it seemed to take forever to download and then update…

Tooks 4 hours and gave up using pc. Just used my Android and turn out okay

Any firewalls, windows firewall, or other firewalls that could be stopping the app from downloading?

Try using tethered connection Hostspot.
