Like most of you, I take it that a 64 bit version of anything will probably run better, faster, process quicker, than the 32 bit cousin. And if you are like me, you will install a 64 bit program on your OS thinking that it will be fine. Of course, if your OS is 64 bit, and your program is 32, it probably will install, but it your OS is 32 bit, your 64 bit program may run into some difficulty.
So getting to IE9 which is available in 32 bit and 64 bit versions. But installing it can be a problem. This is especially so if you are installing your 32 bit IE9 version on your 64 bit Windows 7 version. You may run into the problem that says, “This version of setup doesn’t support your Windows system type (32-bit/64-bit).” So now what do you do?
So here is what Microsoft does to solve the problem, you download both. Actually you only download the 64 bit version. But you install the 32 bit version. How is that possible?
Here is what Microsoft has done. After you’ve installed the 64 bit version, if you look at your All Programs menu, you’ll see, right under Internet Explorer (64-bit) link another option which is “Internet Explorer,” and that’s the 32-bit version. So the 64 bit version is labeled as “Internet Explorer x64″, but the 32 bit version is labeled, “Internet Explorer.”
So if you need to run the 32 bit version, it is already there. So the question is, why did Microsoft pursue this strategy?
The 64 bit IE9 strategy
The main reason that Microsoft enacted this approach was because 64 bit computing is still not the standard. Even though parts of IE9 have 64 bit features, users may find it difficult to use with other applications. So Microsoft offered an approach that would limit the problems that users would have with the browser.
