Running Remote uninstall software 1.0.0.27 (I think it is the latest version)
does not show some programs that are installed.
In this case Bonjour that is not listed in the RUS, but when I search the registry the uninstall string exists under:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{6E3610B2-430D-4EB0-81E3-2B57E8B9DE8D}
This is not the first time an istalled software is not detected with RUS, I think it gets confused by the dual registry posts in a x64 system.
