C:\Program Files (x86)\
In Windows 7 (64 bit) I've noticed a folder called C:\Program Files(x86) - in addition to the more familiar C:\Program Files. I've assumed (maybe wrongly) that this is where 32-bit apps get installed. Today however, I installed what I thought was a 64-bit app but it got installed into C:\Program Files (x86).
Is there a way to tell whether an app is 64-bit or 32-bit? I can't see anything obvious (e.g. in the Properties dialog etc).
