From the log it shows the Qlik Sense version number as 126.96.36.199. I would try downloading the latest release (V2.0.2) and retrying the installation.
Also, can you confirm if you ran this using elevated privileges (right click > Run As Administrator) as the log file shows it was run in an "unelevated" state and this may have also contributed to the issue?
If you are still having problems then I would recommend a call to support.
Hope this helps.
