I was able to get around the installation issue by doing the following found in another post on this site. The issue is with installing sample apps to a mapped network drive which my organization has set-up. Qlik needs to change their installation program to prompt what the user wants installed.
can extract the MSI-files from the exe using:
Qlik_Sense_Desktop_setup.exe -layout "C:\tmp"
There will be a folder named AttachedContainer and in it you will find SenseDesktop.msi and DemoApps.msi. You can then execute SenseDesktop.msi only
