We recently switched our Windows software packages from RPM (cygwin) to MSI (wix). Having a native packaging is a much welcome change and we intend to stick with it. However, MSI feels overly complicated for what it does and doesn't seem to provide some basic abilities. But I'm probably mistaken.

Is there a way to list all installed MSI from the command line ?

this
is a good starting point for you example VB Script from MSDN:
```
```
strComputer = "."

Set objWMIService = GetObject("winmgmts:" & _
    "{impersonationLevel=impersonate}!\\" & _
    strComputer & _
    "\root\cimv2")

Set colSoftware = objWMIService.ExecQuery _
    ("SELECT * FROM Win32_Product")   

If colSoftware.Count > 0 Then

    Set objFSO = CreateObject("Scripting.FileSystemObject")
    Set objTextFile = objFSO.CreateTextFile( _
        "c:\SoftwareList.txt", True)

    For Each objSoftware in colSoftware
        objTextFile.WriteLine objSoftware.Caption & vbtab & _
        objSoftware.Version
    Next

    objTextFile.Close

Else
    WScript.Echo "Cannot retrieve software from this computer."

End If
```
