It's not just Visio or Vista RC1... This is something very sinister
I'm working on rolling out b2TR bits on a number of systems. Well, one of
these has Project Pro 2003 on it - so I first attempt to update that by
uninstalling 2003, installing the b2 2007 bits (not the TR). I get the same
error. My objective was to apply the b2TR bits - but I cannot even get the b2
bits to install.
