Drivers should be installed automatically (by Windows). If you choose to do this manually, if you specify the higher level folder and choose to search sub-directories it should be chosen automatically.
So you shouldn’t need to specify the exact driver files.
The architecture is named after AMD because AMD invented it, with the Athlon 64. Similarly, the 32-bit i386 architecture is named after Intel’s 386 processor, because it was the first of its kind, but i386 will also work on AMD processors.
Even if you have an intel CPU, AMD64 is what you’d use to install 64-bit on your computer (it uses the same instruction sets).
