I have a Kill-Process custom action that seems to work fine if the process I want to kill is running in the same user session. However, if it is running in another session, it doesn't get killed. I need to make sure my application isn't running anywhere on the machine before installing a new version. How can I configure the Kill-Process to take out all copies of the process in any session? Thanks.

I am running with an administrator user. I tried setting the execution to "Deferred" but I got an error "2762 cannot write script record". Based on what I have read online, that option can only be used in the execute sequence, not the UI sequence like I have to use it (see earlier post). The EXE custom action you suggested won't work because I don't have the Product Code of the package I am trying to uninstall. It could be any past or future version of my product. My PowerShell script is looking it up by the application name before uninstalling it. AFAIK, MSIEXEC doesn't have an option to uninstall an application based on its name. What else can I try? Thanks

Thanks Varul, that got me part of the way there. I can use a PowerShell script CA on the NEXT button to do the uninstall. The only problem is that the uninstall doesn't work (return code 1603) unless I launch the MSIEXEC with "Run as Administrator". I have already set the "Require Administrative Privileges" to "Yes" so I don't see why that is necessary. I am running as an administrator and I don't see the UAC message come up. Note that I am using an MSI without Setup.EXE and I need to keep it that way.

OK. So forget about downgrading. How can I set up my installer such that it will uninstall ANY version of my application prior to starting the install? I have tried a PowerShell script in a custom action but that made the installation lock up. Is there a way to do this through InstallScript or something like that? Thanks, Steve

I need to have my installer automatically replace (not side-by-side) WHATEVER version of my application is already on the system. It could be an upgrade, a downgrade or a re-install. I have tried several things to make this happen. I turned off the ISPREVENTDOWNGRADE logic, but that allows a side-by-side installation. I tried creating a PowerShell script to uninstall my application at the beginning of the install. The install locks up. I am always doing a "major" upgrade and that works fine, but I can't seem to get the downgrade to work. I realize that the easiest thing to do is just uninstall the application before installing the older one, but that is unacceptable to my users. I am fairly new to InstallShield so please help! BTW, I am on InstallShield 2021.
