>>32-bit components usually get installed in %windir%\SysWow64 under 64-bit OS (the %windir%\system32 folder is for 64-bit components)

>Knew this and just noticed how confusing this can be. From M$'s perspective, this is quite normal - system32 is where we always put them, even now when they're recompiled as 64 bit (plus we don't even have an inventory of all the places where the location may be hardcoded); the 32-bit components will be put into something with a 64 in its name, because it's, well, what makes them run under 64.

>Imagine if all electric car parts were designed for 6V (as many used to be - the initial versions of VW beetle, for instance) and that every socket had a 6 mark on it. Then they switch to 12 but keep the 6 printed on the sockets... and then have adapters for old 6V parts labeled as 12 because that's what they're for, to make them work under 12V. I'm sure the amount of fried parts would be huge.

and you could see that coming since the days MS switched to System32, leaving some stuff in System but not in a system16...
