Should have warned you about the square brackets ... the forum software uses a version of Wikimarkup for quick editing, and anything in square brackets gets turned into a link (unless you fight really hard).
One thing that looked odd to me is I do have one duplicate entry and I verified it is in the tool. I have two instances of "VC 9.0 Runtime". I don't know if this could be causing a problem or not.
... conceivably it
could ...
Back in the days of ASU 1.x, there was a bug (relating to the Side-by-side configuration) where every time ASU ran, you'd get bunches of Side-by-side error messages in the event logs. That's sort of what I was wondering about when we checked your event logs.
It was a purely cosmetic problem for me, so I never got round to fixing it on my machines which had it.
However, one or two people who were
extremely irritated by it, go past it by installing the Microsoft Visual C++ 2005 Redistributable Package.
So, conceivably, oddities about your Microsoft Visual C runtime installation could be causing the grief here.
If you uninstall one of those VC 9.0 Runtimes, do you get a better-behaved ASU?
If no joy there, if you uninstall
both of them, does ASU behave better? If it does after uninstalling both of them, try reinstalling 9.0 and seeing if ASU still works for you.
