Hi, Eric.
Does your computer have a 64-bit CPU? If not, then it has a 32-bit CPU and
cannot run 64-bit software of any kind, including Vista x64.
A 64-bit CPU can run 64-bit software, but it will also run 32-bit software.
Many (most?) users with 64-bit hardware nowadays have installed 32-bit
Vista, which also limits them to 32-bit applications and drivers.
Starting in the 1980s, Intel named their CPUs 8086, 80186 (rare, but I had
one), 80286, then 386 and 486 - then they called the next one a Pentium.
But by then we had already started referring to the whole family as "x86"
chips. When Microsoft introduced the 64-bit version of Windows XP, they
called it Windows XP x64. And then things got a little confusing. :>(
Instead of calling the 32-bit WinXP "x32", Microsoft started referring to it
as "x86". So, if you don't have 64-bit hardware running Vista x64, then the
x86 version is the one you need. So, get: Windows6.0-KB917607-x86.msu
Vista Home Premium comes in both 32-bit and 64-bit versions. To see which
one you have, go to Control Panel | System. Unless it says "System type:
64-bit Operating System", you have the 32-bit version.
