Auto updater crashes on running?

[Wolverine7]

Are there any hidden prereqs to getting the autoupdating version running? I've installed on my laptop running XP pro and it always pops up the Send/Dont Send error box for crash reporting to Microsoft.

FYI - I do have this program working just fine on my main box running Vista, but for some reason I can't get it to go on the XP machine. Copying known good files from the main box did not work, nor did the self extracting installation file set.
