Thanks for looking into this. The program was stuck, I switched to it and noticed the update prompt waiting, so I updated, thinking it was stuck because the prompt had the focus.The real question is why the installer couldn't get EDMarketConnector.exe to exit to allow the installation to continue. Things are explicitly set up so that the WinSparkle.DLL's code can send a signal for the program to exit.
I'll see if we can explicitly set up the installer to never request/initiate such a reboot though. You're only the second person I know of to be affected by this.
If you could set the installer to warn about not being able to close the program in order to uninstall, possibly giving us the option to kill the process or abort or warn about a necessary reboot, it would be great.
