I don’t know why Sony support is being so fussy over Vista 64. Their web site says they support Vista and Vista 64 is Vista so I don’t see how they can say they don’t support it unless they specifically say Vista 32 only (which they don’t!) Perhaps they mean it won’t take advantage of Vista 64 (which it won’t, it just runs in 32-bit mode)
Just install the software and don’t worry. Vista 64 runs 32-bit applications just fine. I have tons of 32-bit applications running on Vista 64 without any problems. Considering that there are only a handful of 64-bit applications available, Vista 64 would be useless if it didn’t handle 32-bit applications flawlessly.
