Why bother checking if it's running just to kill it.  Do the killtask all the time and if it isn't running it will just fail to kill anything.  If you want to suppress the error message from killtask then you can do:

taskkill /f /im foo.bar >nul 2>%1

Hi underground712,

I agree with billprew, there's no need to check if the process is running.

Anyway, if you really want to check it before you can use this in a batch file:

@echo off
tasklist | findstr "notepad.exe" > nul
if %ERRORLEVEL%==0 taskkill /f /im notepad.exe

Open in new window

Sorry, of course the notepad.exe is wrong in lines 2 and 3, I used this for testing - replace it with jqs.exe

Ditto for replacing "foo.bar" with "jqs.exe"...

it has to be checked, cause just the taskkill is running from zcm10, and script engine reports to the user when installing the application

And we can simplify a little more to get it down to a single line like this:

tasklist /FI "IMAGENAME eq jqs.exe" 2>NUL | find /I "jqs.exe" >NUL && taskkill /F /IN jqs.exe

Open in new window
