wix3.5 - Wix: how to forcefully kill a process/task? -


i need forcefully kill process running in background before attempting delete files, when running uninstall msi created wix. main application consist of trayicon reflects status of bg-process monitoring local windows services (made on c#, though may not relevant going further).

i first tried following:

<file id='fooexe' name='foo.exe' source='..\source\bin\release\foo.exe' vital='yes' />      ... <installexecutesequence>   <custom action="closetray" before="installvalidate" /> </installexecutesequence> ... <customaction id="closetray" execommand="-exit" filekey="fooexe" execute="immediate" return="asyncwait" />

the tray icon closed after confirming application-close dialog, foo.exe task still appears on taskmgr after uninstall completed. also,the following error message given:

error message #1

thats why, tried this:

<installexecutesequence>   <custom action="foo.taskkill" before="installvalidate" /> </installexecutesequence> ... <customaction id="foo.taskkill" impersonate="yes" return="asyncwait" directory="windir" execommand="\system32\taskkill.exe /f /im foo.exe /t" />

after obtaining same result, tried:

<property id="qtexeccmdline" value='"[windir]\system32\taskkill.exe" /f /im foo.exe'/> ... <installexecutesequence>   <custom action="myprocess.taskkill" before="installvalidate" /> </installexecutesequence> ... <customaction id="myprocess.taskkill" binarykey="wixca" dllentry="caquietexec" execute="immediate" return="ignore"/>

sample took here: how kill process wix

lately when else failed, tried without success:

<wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:util="http://schemas.microsoft.com/wix/utilextension"> ... <installexecutesequence>  <custom action="wixcloseapplications" before="installvalidate" /> </installexecutesequence> ... <util:closeapplication id="closefoo" closemessage="yes" description="foo still running!" elevatedclosemessage="yes" rebootprompt="yes" target="foo.exe" />

this 1 gave me different error:

error #2, doing wrong here?

i'm thinking on building statue in honor process refuses die!!! ... either or think problem on application side exists, should add application.exit(); or environment.exit(0); @ line inside program.cs.

is there other thing @ either wix or application attempt closing @ uninstall? thanks!

personally think best option go in-built closeapplication method rather previous options.

the error getting (error code 2762) because trying schedule action in immediate sequence have elevatedclosemessage="yes" set triggers deferred action. either remove attribute or schedule in deferred sequence.
