kill a process before uninstall an app
Any tips on how to do this? I did not create the MSI, and it wont uninstal unless a process is killed first.

You need to add a Custom Action, conditioned to run only during an uninstall (REMOVE~="ALL"). You'll find your best option is a VBScript-driven CA, as there are a quadzillion examples of scripts around which kill processes. Make sure, however, that any script you use is properly error-trapped.

You could also write a simple AutoIT script to detect and kill the process before it runs the installer.

Cheers thanks. I know if I want a custom action at install time where I did not create the msi, I call it with a transform, I can't call a transform at uninstall?

If you have a vendor MSI then you should create a transform and add the custom action to Kill Process in the transform. As VBScab mentioned it should be set with condition REMOVE~="ALL" which will run during uninstall.
I usually sequence if before AppSearch with a Execution Property set to Synchronous and Execution Option set to Immediate.

Hi,
Before uninstallation check the application is running
TASKLIST | FINDSTR /I "application.exe"
if the application is running , kill the application and uninstall.. I hope it will help you

TASKLIST | FINDSTR /I "application.exe"Too messy. Most of the process-killing scripts around use the WMI object to enumerate the process list and, when the target process is found, get its process ID, using that to terminate the process. Avoid those scripts which kill named processes: always use the process ID. You can hopefully work out why.

Hi VBScab,
If we kill the process , by process name, there is danger of termination of other processes related to the application also.
If we kill the process by using process id, which unique for the application, we can avoid above problem.
Thatswhy we cant use processnames to kill the application . Is it?[:o]

Thanks for your help guys. I have cracked it. I would have done as VBSCAB suggested however my process has a different PID each time it runs, so I don't see how I could.

Then I guess you have no choice but to use the Process Name unless anyone else can come up with a better solution. Here's an example, just replace the exe..
Make sure that terminating this process has no linkage to the others as mentioned by VBScab and Shakeela511
On Error Resume Next
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colProcessList = objWMIService.ExecQuery _
("SELECT * FROM Win32_Process WHERE Name = 'YourRunningApplication.exe'")
For Each objProcess in colProcessList
objProcess.Terminate()
Next

I changed my mind. My mind was on process creation, as I'm building a script at the moment which creates and monitors a process's execution. For that, I need the process ID, as there may be another instance (or instances) running.
For process termination, it wouldn't matter if there's more than one instance since, if you need to kill Fred.EXE in order to replace it, you would clearly need to kill all instances of it.

Without question, command line tools, especially ones of quality such as those from SysInternals, work. However, they are more suited to one-off - what I call QAD (Quick And Dirty) - usage. For a more professional approach, script is the way to go, since to describe error-trapping and conditional branching in batch/command files as "primitive" would be more than kind.

Hence the VBScript just shelling out to run PSList & PSKill - not running from a batch file. Not an ideal solution, but it works exactly a required.

If the process (file) is installed by the package then I would also (before executing the kill) get the path of the file and use that in the wmi query to make sure the process is part of the package and not any "random" process.
