Maybe I didn't explain this well. Anyway I found a solution.
After searching my install log I found a very handy property:
CLIENTPROCESSID.
CLIENTPROCESSID is the process ID of the msiexec.exe that is working with
the loaded msi database.
I added this property to the wix project:
<Property id="COMMANDLINE"/>
Added the below Custom Action:
<CustomAction()>_
Public Shared Sub GetCommandLine(ByVal session As Session) As ActionResult
Try
'Get all Win32 processes
Dim mngmtClass As ManagementClass = New
ManagementClass("Win32_Process")
For Each o As ManagementObject In mngmtClass.GetInstances()
'weed out the needed msiexec.exe
If o.GetPropertyValue("ProcessId").ToString =
session.item("CLIENTPROCESSID") Then
'Get entire command-line
session.item("COMMANDLINE")=
o.Properties("CommandLine").Value.ToString
Exit for
End If
Return ActionResult.Success
Catch ex As Exception
#If DEBUG Then
MsgBox(ex.Message & " @ " &
Reflection.MethodInfo.GetCurrentMethod.Name)
#Else
session.Log("Error: {0}", ex.Message)
#End If
Return ActionResult.Failure
End Try
End Sub
It works!
Now back to why I needed this in the first place.
Both msiexec /passive /x {ProductCode} and ARP uninstall cause the msi to
uninstall at UILevel=3
Now I know if the user supplied the /passive switch or if the user initiated
a normal uninstall.
My tests confimed that:
COMMANDLINE = 'C:\...msiexec.exe /i {ProductCode}' during normal ARP
uninstall
COMMANDLINE = 'C:\...msiexec.exe /i {ProductCode} /passive' when the user
supplies the switch
