Good work Rev, I wonder where Don is from, perhaps it could be a starter edition of windows, or some regional issue.

Im assuming they have exited IE before trying to install Flash. I would try the full uninstall again, and then just go to adobe.com/flash and theoretically it should detect the missing activeX and pop-up to allow the installation.

Also, is there Spybot running with the IE lockdown.

Very interest case though.
