I'm new to wix and msi but it looks like you'll need to use a custom action, you could call into a dll or write a vbscript (it looks like using scripts in custom actions may be frowned upon), anyway you can set a property to a new guid and then reference that, the simplest example would be with a vbscript custom action.
<Product ...> ... <Binary Id="VbScriptKit" SourceFile="VbScriptKit.vbs"/> <CustomAction Id="CreateUserGuid" Return="check" BinaryKey="VbScriptKit" VBScriptCall="CreateUserGuid"/> <InstallExecuteSequence> <Custom Action="CreateUserGuid" After="CostFinalize"/> </InstallExecuteSequence> ... </Product> --- VbScriptKit.vbs (make sure this is ASCII) Option Explicit Function CreateUserGuid() Session.Property("USERGUID") = Mid(CreateObject("Scriptlet.TypeLib").GUID, 2,36) CreateUserGuid = 1 End Function --- you should make the function more robust but it's just an example. Here's the relevant snippet of the install log: Action ended 21:49:36: CostFinalize. Return value 1. MSI (s) (74:20) [21:49:36:716]: Doing action: CreateUserGuid MSI (s) (74:20) [21:49:36:716]: Note: 1: 2205 2: 3: ActionText Action start 21:49:36: CreateUserGuid.

Return value 1. Obviously you can do what you want with the USERGUID property, hope that helps.
