Need to know where you are installing Qliksense? on Server or desktop?
If on desktop than both will work together..
if on server and trying to install full server setup than Qlikview and Qliksense will not work together bcoz they required almost same configuration like port etc.
you must have to uninstall qlikview to install Qliksense Server. and make sure port 80 and 443 must be free before installing. and If Skype is preinstall than you need the change the port of Skype..
Hope it helps
You can use port 80 for accessing Qlik Sense content however if you intend to authenticate your users with the out of the box windows authentication you will need open port 4244.
The authentication port is configurable however but I don't believe you can share port 80 for it. Perhaps you can use port 8080 instead?
