Desktop Client: Why is iGrafx installing into a "Program Files (x86)" folder on my 64 bit Windows?

On Windows 64-bit operating systems, there are two Program Files folders; one for 32-bit applications (the "Program Files (x86)" folder) and one for 64 bit applications (the "Program Files" folder). Applications such as iGrafx FlowCharter will install themselves into the 32 bit 'x86' folder if they are 32-bit applications. Said another way, if iGrafx is installing into the "Program Files (x86)" folder, you are installing the 32-bit version of an iGrafx application.
