Sure.
Script detection methods: If the script returns ANYTHING, the detection method
believes the deployment type has been detected. So, for this, our script needs
to check for the registry key, and if it DOES NOT exist, it should return
something. If it DOES exist, the script needs to return nothing (and I mean
absolutely
nothing<http://www.david-obrien.net/2013/12/19/configmgr-powershell-application-detection-methods/>).
A PowerShell example might look like this:
If (Test-Path
"HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft Mouse and
Keyboard Center") {} Else {Return $True}
Or, you could use this to keep from being tempted to fill in that first {} with
something:
If (-Not (Test-Path
"HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft Mouse and
Keyboard Center")) {Return $True}
Reminder: If you use this application in a Task Sequence, you'll need to make
sure you change the script execution policy for the system before that step.)

Can you show me an example of that? I've always heard it suggested but have
never done it or seen it done.

Since the built in detection methods require something to exist (file, registry
key, product code), you can't really evaluate that something does not exist.
In this scenario where your 'install' is actually an uninstall, you can use a
Script detection method.

Subject: [mssms] Detection method for uninstalling Groupwise Messenger
What is the best method when uninstalling software? I need to uninstall
Groupwise Messenger on all workstations/servers and I'm getting stuck on
detection method. How do I create a detection method that tells me the
uninstall went through?
Or should I just build a package with the uninstall command line and do it that
way?
