Via VBScript custom action:
' open the MSI database of external package
Set installer = CreateObject("WindowsInstaller.Installer")
path = Session.Property("SETUPEXEDIR") & "\name.msi"
Set database = installer.OpenDatabase(path, msiOpenDatabaseModeDirect)
' setting new product code
newProductCode = GetNewGUID()
insertQuery = "UPDATE `Property` SET `Value` = '" & newProductCode & "'
WHERE `Property` = 'ProductCode'"
Set insertView = database.OpenView(insertQuery)
insertView.Execute
insertView.Close
' changing the package code
set info = database.SummaryInformation(20)
info.Property(9) = GetNewGUID()
info.Persist
' changing components' IDs
ChangeComponentID "WebSite", database
ChangeComponentID "MSSQLDatabases", database
' etc.
' making the changes persistent
database.Commit
Whereas the ChangeComponentID is defined as follows:
'Helper function: changes the ID for a component
Function ChangeComponentID(componentName, database)
Dim newComponentID, insertQuery, insertView
newComponentID = GetNewGUID()
insertQuery = "UPDATE `Component` SET `ComponentId` = '" &
newComponentID & "' WHERE `Component` = '" & componentName & "'"
Set insertView = database.OpenView(insertQuery)
insertView.Execute
insertView.Close
End Function
Hope this helps.

Hi Yan
I wonder how did you 'patch' the second package with new Guid.

I had the same problem once and here's how I solved it.
I split my installation project into 2 projects: the first one is a
so-called UI part, the second one is the main project and it actually
installs the product.
The UI part gathers the information from the user and the target system
as usual, then opens the MSI database of the target package, "patches"
it with new GUIDs, starts the main installation as msiexec /I
<list_of_public_properties> and silently closes itself. In such case
every time you install your product, from the system point of view it
launches a different MSI package each time.
I'm not sure if it is the way to go for your case and if it's at all the
WiX-like approach. But when I was searching for the solution to this
problem, this is the best advice I managed to get.
Hope this helps.

I don't think that this is possible because of the GUIDs which would
have to be different every time you install the package.
Try to build an installer which copies the same files into different
locations instead.

Subject: [WiX-users] Wix multiple installs
Hi
I am trying to create WIX install that could be installed multiple times
on one machine. To explain myself better I need to be able to install
the same application on one computer several times in different
locations (there is a good reason for this). Currently every time I
install new into a new location it uninstalls the application in the old
location and there is only one entry in the instaled application windows
(Add or Remove Programs) where I would like to have as many entries as
installed applications.
I wonder if its possible to do it and if anyone knows how I would
appreciate any hints.
Regards
Daniel
