x86? x64? ia64?

[jediness]

Hi. I'm working on installing .NET Framework here:
http://msdn2.microsoft.com/en-us/netframework/aa731542.aspx
This is my CPU:

I read a little bit and saw that means Intel Itanium. I don't know if that's a specific CPU or class of CPU that mine is categorized as.
Could anyone help?
Thank you for your time.

*edit
I mean "ia" means Intel Itanium but I don't know which is the right option.

I researched and found out it's an x86_x64, which was really not helpful in knowing which one to pick lol. I tried x64 and it didn't work. I chose x86 and it did. So, the answer: x86

Intel Core 2 Duo chips are x86. What you are looking at is the instuction set of the processor that you own. x86 is probably the most common, with other RISC chips coming in second. I'm not familir with x64 or the itanium instruction sets but I would imagine they would be much larger then x86. Also most program built for an x86 machine will work on an 64 bit machine which leads me to belive that the 64 bit instruction sets are a superset of the x86 instructions.

Since you are woking with an interpreted language (ie. the .net framework) you will not need to be concerned when creating programs. The .net framework is designed to be portable between different archetectures.
