What I see from the screen shot is that your entry looks quite different than my GIMP installer (I am using GIMP Windows installer from <http://gimp-win.sourceforge.net/stable.html>, 32-bit only). However the registry path on my machine points to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\WinGimp-2.0_is1 well, the Wow6432Node tree is because of Vista x64 registry mapping So the 32-bit path should be HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\WinGimp-2.0_is1 Looking at the log below I am absolutely sure that WPKG finds a DisplayName entry within the uninstall locations which carries the string "GIMP 2.6.5".

WPKG clearly says that your registry contains an entry with a DisplayName of "GIMP 2.6.5". Try looking for that string within your whole registry. br, Rainer |
