This problem has nothing to do with the fact that you are using a Mac and a Virtual Machine. It is the correspondence between the Windows OS 64/32/pre/post 8.0 and the installation file for QlikView.
If you have a 32-bit Windows you have to install a 32-bit version of Qlikview. I guess that you are trying to install the 64-bit Desktop client on a 32-bit Windows OS in your virtual machine. That would give you such an error message.
