Gimp

These are silent installer entries for GIMP, GIMP-Help and GTK (available from http://gimp-win.sourceforge.net/stable.html):

NOTE: /SILENT Shows progress, /VERYSILENT is truely SILENT and has no dialogue boxes at all (running the gimp .exe with /? reveals all the switches).

GIMP 2.6

<?xml version="1.0" encoding="UTF-8"?>
<packages>
  <package
    id="gimp26"
    name="GNU Image Manipulation Program (GIMP)"
    revision="2608"

Gimp 2.6 for Windows does not come with the Help Browser, however by default Gimp is configured to use the Help Browser. To correct this add the following.

 <install cmd='"%SOFTWARE%\gimp\gimp26_prefs.bat"' />
 <upgrade cmd='"%SOFTWARE%\gimp\gimp26_prefs.bat"' />

REM gimp26_prefs.bat
echo (help-browser web-browser) >> "%PROGRAMFILES%\GIMP\etc\gimp\2.0\gimprc"
echo (user-manual-online yes) >> "%PROGRAMFILES%\GIMP\etc\gimp\2.0\gimprc"
REM Other defaults can also be defined here.  Possible defaults are documented in gimprc.

  <!-- Download: http://downloads.sourceforge.net/gimp-win/gimp-2.4.6-i686-setup.exe -->

  <check type="uninstall" condition="exists" path="GIMP 2.4.6"/>

  <install cmd='"%SOFTWARE%\gimp\gimp-2.4.6-i686-setup.exe" /VERYSILENT /NORESTART /DIR="%PROGRAMFILES%\GIMP"'/>

  <remove cmd='"%programfiles%\GIMP\setup\unins000.exe" /VERYSILENT /NORESTART' />

GIMP-Help doesn't create an Add/Remove programs entry.

GTK

• http://sourceforge.net/project/showfiles.php?group_id=121075

<package
  id="gtk"
  name="GTK"
  revision="0"
  reboot="false"
  priority="0">

  <check type="file" condition="exists" path="%COMMONPROGRAMFILES%\GTK\2.0\bin\libgtk-win32-2.0-0.dll"/>
  
  <install cmd="%SOFTWARE%\gimp\gtk+-2.6.9-setup.exe SP- /SILENT /NORESTART"/>

  <remove cmd='"%CommonProgramFiles%"\GTK\2.0\unins000.exe" /SILENT'/>

</package>

Note that the check condition here relies on a version-specific file which could change, libgtk-win32-2.0.0.dll.

Package for newer gtk-2.10:

<package
  id="gtk"
  name="gtk+ 2.10.11"
  revision="1"
  reboot="false"
  priority="0">

  <check type="uninstall" condition="exists" path="GTK+ 2.10.11 runtime environment"/>

  <install cmd='%SOFTWARE%\gimp\gtk+-2.10.11-setup.exe SP- /SILENT /NORESTART'/>

  <remove cmd='"%CommonProgramFiles%"\GTK\2.0\setup\unins000.exe" /SILENT'/>

</package>
