MS technotes never cease to piss me off with typos and such:
To temporarily work around this issue, move the Msdia80.dll file to the Drive:\Program Files\Common Files\Microsoft Shared\VC folder.
regsvr32 driver:\Program Files\Common Files\Microsoft Shared\VC\msdia80.dll
They need to employ people who know what the technotes mean, not someone typing from a phone call. Seen far worse on the MS site though.
