For QV9 Desktop, only the x32 version support Itanium processor. Taken from the reference manual:-
QlikView 9 does not ship in a native IA-64 (Itanium) version. The
32-bit version will run on Itanium based machines with Windows,
but performance can be expected to be poor. For native 64-bit
Itanium support we refer you to use QlikView version 7.xx.
