Update, Gave up on Windows 7. Support were good and let me know that I had maxed out on windows Certificates (Qlik Sense wont add Certificate if you have more than 250 on your pc).
Went to plan B used Virtualbox and 180 day trial of Win 2008.
Works fine within Virtualbox.
Next stop was trying to access from a browser on Windows 7 (Note don't forget to set up a user token)
Turned off firewall within 2008 and spend some time to not getting anywhere.
Discovered an error message when looking at 2008 network troubleshooting - I had 2 NAT's running which would be a conflict.
Switched from NAT to Bridge within Virtualbox.
Was attempting to use IP connection like this: https://10.11.12.1/hub
Fiddled with 2008 and gave it a static IP address that matched the network and also set the domains to match.
Also changed the network setting to home instead of public.
Finally accessed Qlik Sense via https://win-qlik/hub win-qlik being the name I gave to Win 2008 during install.
So final task is to turn Windows Firewall back on to add some security.
Hope these helps anyone else faced with a similar install problem.
