32-bit ProcessClose in 64-bit world

[odatbret]

I have a 32 bit application running on a Windows 2008 Server 64-bit OS. The application is launched by an automated process and thus not windowed. While I am able to list the process and get the PID, the processclose function does not kill the process. Any ideas?

Thank you.

You have to have sufficient rights to close application. Which in particular depends on many factors.

You should provide more specific informations to get more specific help.

A 32 bit process cannot access 64 bit processes. You must have your app to be compiled to x64.

Using x86 Autoit's ProcessClose works alright here for closing x64 process, so that not the problem.

what's the output, if you try taskkill.exe with force option on that process?

I've tried this actually, and I could never find anything to work either, here's a batch example of one of the ones I tried it with.

@ECHO OFF
TASKKILL /IM Vindictus.exe /F /T 
del C:\Nexon\Vindictus\en-us\HShield\hshield.log
del C:\Nexon\Vindictus\en-us\HShield\supdate.log
del C:\Nexon\Vindictus\en-us\HShield\HSUpChk.log
del C:\Nexon\Vindictus\en-us\HShield\Update\supdate.log
cd %UserProfile%
rmdir /s /q "Documents\Vindictus\Report Error"
ECHO Done.

no matter what happens, vindictus would never close. I've made other applications do it, but all those were x64

Thanks to all who replied. It's given me a few other ideas to try, most notably the taskkill.exe tool I did not know about before. Just in case that approach does not work, here are some more details.

1. I am logged in as a member of the local administrators group on the server and have sufficient rights to stop processes as I am able to manually kill the process using task manager.

2. The application, when launched in a non-automated fashion, is a windows app and has window titles that can be determined with the wingettitle command. The application and it's related processes can also be killed using the winkill or the processclose command in this setting. The processclose command fails to kill the process if the application was launched based on a task scheduler event and is a visible window.

3. I have compiled the autoit script for x64 and am using the very latest non-beta versions of autoit.

The processclose command fails to kill the process if the application was launched based on a task scheduler event and is a visible window.

When you launch an application with a task scheduler event, it is run with the "System"-Account. No other user has the right to kill it. You will have to create another task to kill it or run an AutoIt-script as the task which launches the app and later kills it.

It took a few tries with the command line syntax, but the taskkill.exe route did the trick where processclose was failing. The final piece of the puzzle was the use of the /f and /t flags on the command lines and ensuring the password was enclosed in quotes as it contained some special characters that the command interpreted as invalid parameters. Below is the code I used with the sensitive items renamed (user anmes password, etc). As noted in previous replies, this process did require the use of administrator level credentials.

Hope this helps anyone else who encounters a similar issue.
