[wpkg-users] Testing is a specific process is running

[LAPLAUD François]

Here is the beginning of my package.

<?xml version="1.0" encoding="UTF-8"?>
<packages>
	<package 
		id="firefox4"
		name="Mozilla Firefox 4"
		revision="%version%"
		reboot="false"
		priority="10"
		notify="false">
		<chain package-id="flashplayer_mozilla" />	 
		<variable name="version" value="4.0.1" />
		<variable name="architecture" value="x86" />
		<variable name="locale" value="fr" />
		<check type="uninstall" condition="exists" path="Mozilla Firefox %version% (%architecture% %locale%)" />

		<install cmd='%COMSPEC% /c %SystemRoot%\system32\tasklist.exe /FI "IMAGENAME eq firefox.exe" 2>NUL | %SystemRoot%\system32\find.exe /I /N "firefox.exe" >NUL'/>
		<install cmd='"%SOFTWARE%\packages\Firefox\Firefox Setup 4.0.1.exe" -ms' />

Here is the log when firefox is not running.  :

Hello,

Strange, for me with a test package using your line below, it works. 
What's you xml file look like, my test install is below (installing dia 
install):

<?xml version="1.0" encoding="UTF-8"?>
<packages>

<package id="test" name="testing 123" revision="1" reboot="false" 
priority="63">

         <variable name="proc" value="firefox.exe"/>
         <variable name="version" value="0.97.1" />

         <install cmd='%COMSPEC% /c %SystemRoot%\system32\tasklist.exe 
/FI "IMAGENAME eq %proc%" | %SystemRoot%\system32\find.exe /I /N 
"%proc%" >NUL' />
         <install cmd='%SOFTWARE%\graphics\dia\dia-setup-%version%-2.exe 
/S' />

</package>

</packages

Changing

<variable name="proc" value="firefox.exe"/>

  to

<variable name="proc" value="firef.exe"/>

stops dia-setup-%version%-2.exe from being installed as expected. 
Correcting the firefox.exe variable, dia gets installed.

Cheers
