I am going to take a stab at this and say you are trying to run 16bit DOS programs?  If so, 16bit apps cannot run on 64bit versions of Windows, you will need a DOS emulator like DOSBox.  Otherwise, what sample apps are you having trouble with?  NASM works fine on 32 and 64bit systems.

I wanted to ask here because I dont know how to install 64 bit version. Please anybody help me I'm new to this. I really need this and don't know where to ask for help.

I have the same exact problem.  What kind of error message are you getting?

If you have the exact same problem, you ought to know! :)

Seriously, guys, we need more information. What did you do? What did you expect to happen? What happened instead?

If this is "the 16-bit problem", even I can't blame Microsoft for it. When we put the CPU in "long mode" (64-bit), "v86 mode" (which is what WinDOS has been running in for ages) is no longer available. Blame AMD, I guess, or perhaps the laws of physics. AFAIK, 32-bit programs should run in 64-bit Windows. That would include Nasm itself - I don't think we provide a 64-bit build of Nasm. There may be issues I'm not aware of. Tell us about it!

You should find 64-bit examples in the "Example Code" section (mostly thanks to Encryptor256 - Thanks!).

As "Number Five Is Alive" says... "need input", "need input"...

Best,
Frank
