This is probably because the "Qlik Sense Desktop" is not started.
You must start the Qlik Sense Desktop "QlikSense.exe".
The default installation location is "C:\Users\your user\AppData\Local\Programs\Qlik\Sense\QlikSense.exe".
Please note that the Free Qlik Sense Desktop tool - is for Personal and Individual business use. If you require a solution that is web based and offers the same capabilities as Qlik Sense Desktop - including management, administration, security, governance and auditing, reload scheduling - you will be interested in the Qlik Sense Server, licensed software. We do not price our software by server, we use a token licensing model - which allows you to manage your users and their usage types. You can contact our Contact Qlik Qoncierge Service | Qlik - -which can help with additional pricing and licensing questions.
