I am trying to change the packagecode of my msi project at build time. I am trying to use VBScript to do that and have tried to follow the windows installer documentation but I have not been successful. I am not even able to read the package code.

Here is my code snippet:
Set installer = Wscript.CreateObject("WindowsInstaller.Installer")
Dim sumInfo : Set sumInfo = installer.SummaryInformation(<path to my installer>, 1)
value = sumInfo.Property(9)

9 is the PID_REVISIONNUMBER which is supposed to have the package code.

When I print out the value, there is nothing there.

Can someone please help?

That is the weirdest thing!

I ran some MSDN code against one of my MSIs and got all the properties I requested first time. Subsequent runs, however, returned no properties at all. When I switched to interrogating another MSI, I once again got all the properties.

Then I checked the SDK sample scripts, specifically WiSumInf.VBS. Check out the use of the 'cUpdate' variable in that sample.
