Difference between Server version x64 (64bit) and x86 (32bit)
Dear community members,
We are using the QlikView Server Version 11.20, Release SR13. I see that there are different versions: x64 (64bit) and x86 (32bit).
I understand that one version is to be installed in 64 bits machines and another to be installed in 32 bits machines. However we have installed the 32 bit version in a 64 bit machine and it all worked fine. The application is working perfectly.
I would then like to know, what is the real difference between the two versions? Is it just a matter of performance optimization or some functionality difference?
The 32bit version will be limited to using 4GB of memory. Not because we want that, but that is just simply the technical limitation of a 32bit machine. That's it.

If I'm not mistaken, you can install almost every 32-bit Windows application on a 64-bit operating system. The application will then interface with Windows using an API layer called SysWOW64 that makes the 64-bit machine look like a 32-bit machine to all 32-bit applications. As a result and just like Onno already stated, your application will never be able to use more resources than what the artificial 32-bit environment allows for, even when your 64-bit system has 100's of Gigs of free memory.
Better install the 64-bit version of the software.
