Zwift wont open after install on new PC

As title says. I click the icon and nothing happens. Tried running as admin and still nothing. I’ve googled it and nothing has worked. Totally stumped.

I’d try an uninstall, reboot and re-install and see if that helps. I assume other programs run and start ok?

Did all that. Got it working though. I couldnt delete the Zwift files in document because one drive wasn’t signed in.
