Question

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 ?

Mabybe 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
