I have noticed that for Qlik Nprinting 17.3.1 and 17.4, there is no way to specify the installation location. It was possible in previous version (16 if I remember well). Instal run in admin mode, of course, by an account in local Administrators of server. Nprinting for Qlikview, in case there is a difference with the one for Qlik Sense.
It is a real pain in the neck for organization that have strict deployment norms.
Thanks a lot if you have any pointer.
Same issue on :
Windows 2012 Server 64 + Qlik Nprinting 17.4
Windows 7 64 + Qlik Nprinting 17.3.1
It seems it was the same for 17.2 : Qlik NPrinting Install Location
