The reason is probably because they are 32 bit applications. If it is an actual 64 bit it should go into "Program Folder." All 64 bit applications installed on my system have gone into "Program Folder" with the exception of iTunes, which for some reason it does not see iTunes as a 64 bit program. In fact in "Task Manager" iTunes.exe is seen as 32 bit even though the download indicates it is 64 bit. Albeit iTunes is the only application that does this; Photoshop CS4, Lightroom, MS Office 2010 64 bit, etc., all have loaded into the "Program Folder" without a problem. Now having said that, Adobe CS4 products come in both 32 and 64 bit (on the same disk), hence, it loads both onto the computer, their 32 bit go into "X86 Programs Folder", and 64 into the "Program Folder."
