Are you installing a fresh copy? Meaning previous version is uninstalled and then installing a newer version?
What version are you trying to install? 2.0.4? or 2.1?
I have seen this error most of the times in my event viewer too but that didn't caused any issues. Meaning all my services are running ok and i was able to access HUB & QMC.
I had this same issue initially. In my case, I need to install the Microsoft Visual C++ 2010 Redistributable Package. I believe that the Qlik Sense installer is trying to detect if this is installed but failing for some reason. Remove Qlik Sense, install the Microsoft package and then reinstall Qlik Sense.
That worked for me.
