enes,

       I can say, with absolute certainty, that at one point (probably in the past) Microsoft explicitly instructed to use the 32-bit version of Office unless you needed something that could not be had without the 64-bit.

        But, my statement is about what we techs "on the ground" routinely advise, particularly after an issue has reared its ugly head with a 64-bit version of anything.  For lots of stuff I still just install the 32-bit because it's the "most focused upon" in the development cycles at the moment.  That's definitely going to change, and I wish it had changed ages ago, but there has always been a need to keep the 32-bit stuff "in tip top shape" since it can run under a 32-bit and 64-bit version of Windows.

        There's lots of 64-bit software, I'd say most of it, that you won't have a single, solitary problem with.  But if you are, or suspect you might based upon reports such as those made in this topic, and a 32-bit version exists, then nuke the 64-bit install and then install the 32-bit version.
