Chuck had installed it on 64-bit maybe 8 months ago. We often install on common drive, missing PF(32). So he basically lucked into, and we didn't think much about it.
A couple months ago, I had reason to look whether 64-bit was compatible with FRX, and Google search turned up MS posting of the update that was almost 2 yrs old, so I figured that this was ""a previously solved problem"" and didn't want to ask stupid questions. That's when I discovered that the MS release is doesn't fully work with Sage. Again, we basically lucked into the solution because we this last install was on the AppEazy Data drive, and therefore not in pf(32).
So by not much more than serendipity, we never thought much about the problem .... that was driving lots of folks nuts! There's a lesson in there somewhere.
