[wpkg-users] GIMP upgrade

[Hubert Kühne]

Hi, 
I can not upgrade gimp. Every computer produced this ERROR

2009-07-09 10:08:36, DEBUG   : Executing command: %COMSPEC% /c "%SOFTWARE%\gimp\gimp-2.6.6-i686-setup.exe" /NORESTART /DIR="%PROGRAMFILES%\GIMP" >NUL 2>&1
2009-07-09 10:08:37, ERROR   : Could not process (upgrade) package 'GNU Image Manipulation Program (GIMP)' (gimp26):|Exit code returned non-successful value (1) on command '"%SOFTWARE%\gimp\gimp-2.6.6-i686-setup.exe" /NORESTART /DIR="%PROGRAMFILES%\GIMP"'.

How can I find out, what is and what couses "exit code 1".

I tried manualy to start '"%SOFTWARE%\gimp\gimp-2.6.6-i686-setup.exe" /NORESTART /DIR="%PROGRAMFILES%\GIMP"' and I was successful.

Here my package:
<package
  id="gimp26"
  name="GNU Image Manipulation Program (GIMP)"
  revision="2606"
  reboot="false"
  priority="20">
  <check type="uninstall" condition="exists" path="GIMP 2.6.6"/>
  <install cmd='"%SOFTWARE%\gimp\gimp-2.6.6-i686-setup.exe" /VERYSILENT /NORESTART /DIR="%PROGRAMFILES%\GIMP"'/>
  <upgrade cmd='"%SOFTWARE%\gimp\gimp-2.6.6-i686-setup.exe" /VERYSILENT /NORESTART /DIR="%PROGRAMFILES%\GIMP"'/>
  <remove cmd='"%programfiles%\GIMP\setup\unins000.exe" /VERYSILENT /NORESTART' />
</package>
