[Paraview] Which QT for 64-Bit Version for Windows

[Michael Jackson]

I usually use a self-built Qt 4.6.2 with ParaView. I have to admit  
that I have not done this in a while though, since maybe ParaView  
3.6.2 days. I don't think I have ever had any problems with a self  
compiled Qt and ParaView on any platform and operating system (Windows  
32 XP, 7 x64, OS X, Linux).

    In order to build a 64 bit ParaView you will need a 64 bit Qt. The  
question is, do you really _need_ a 64 bit ParaView? Just because you  
are running a 64 bit Windows doesn't mean you need to run a 64 bit  
ParaView. You would need a 64 bit ParaView IF you are accessing Data  
sets larger than 2GB or have a HUGE pipeline that will need more than  
the 2GB limit of 32 bit processes**

** Really, you only have about 1.4 GB of workable memory on a 32 bit  
Windows, at least according to my experiences.
