Mr. X: I don't know what you are trying to say here, no 32bit packages "not recommended" on 64 bit OS? Office 2007: All 32bit, runs perfectly on 64 bit Win7. By design. Office 2010: Mostly 32 bit apps, but you can install 64 bit editions of several individual elements, Excel is one example, giving you larger spreadsheet row/coumn counts (as a start). 32bit apps work perfectly. Adobe Production Premium CS4, mostly 32 bit apps, but you can install the 64 bit version of Photoshop. The 32 bit apps work perfectly. Far Cry 2: (Game) Installs completely in the Program Files(x86) folder, works perfectly. In fact most things on my (6) Win7 x64 machines are 32bit apps, and I'll bet the same is true for your system. It in fact is WHY the Program Files (x86) folder exists. Are you sure you didn't mean 16bit apps? The only reason x64 is finally becoming mainstream is BECAUSE it runs 32 bit apps. The one distinction is drivers. Yes, you need to be running 64 bit drivers for the most part, this is the one stumbling block that gives most people problems. If a vendor refuses to provide 64 bit updates to drivers for older hardware, it almost certainly means THAT hardware is "obsolete" as far as 64 bit OS's are concerned. DAS

Note that running 32 bit packages on a 64 bit OS is not recommended. Yeah, that's bogus advice just as stated - it's far too general. There are certainly a few things that are 32 bit-specific, such as certain antivirus packages (which are very operating system-specific by nature), that wouldn't make sense to install on a 64 bit OS, but as noted above virtually all 32 bit applications will run great on a 64 bit OS. Microsoft really did up the compatibility right in their 64 bit OSs, to ease the transition. -Noel
