Sascha's point is that you can save this yourself if you really want to get it from the registry. ProductID might be the better property to change because it's been through any verification that might be done by ValidateProductID. However if you've already shipped the original it's too late, which is why upgrades need a sanity test before the original actually gets out the door.
My point is that if you don't want to do that, then a custom action can call MsiGetProductInfo. You don't pass parameters anyway. http://www.wixwiki.com/index.php?title=Simple_Custom_Action_Dll and you'll do a MsiGetProperty ("ProductCode" ...... ) and then MsiGetProductInfo for "ProductID" on that returned product code, then MsiSetProperty (handle.... "MYOLDPIDKEY" ....) to set the value into the MYOLDPIDKEY property, but there's no reason why you can't set PIDKEY. Since you're doing this on an upgrade of some kind you'd condition this CA call on the property in the Upgrade table.

Subject: Re: [WiX-users] Read ProductID (PIDKEY) from registry It appears to be a property set by MSI in a location with a strange GUID. In brief: I cannot find logic between the application and the place MSI puts this parameter. I need to make a customaction call to the "MsiGetProductInfo" method in "msi.dll", passing some params. However, I've still not found how to call a dll method, passing parameters :-s -----Oorspronkelijk bericht----- Van: Sascha Beaumont [mailto:[email protected]] Verzonden: donderdag 5 november 2009 0:53 Aan: General discussion for Windows Installer XML toolset. Onderwerp: Re: [WiX-users] Read ProductID (PIDKEY) from registry Assuming that PIDKEY is just a property you're setting, you'll probably want to set the property to a default value (e.g. DEMO) and do a RegistrySearch to overwrite it if you can find an existing PIDKEY in the registry. <Property Id="PIDKEY" Admin="yes" Secure="yes" Value="DEMO"> <RegistrySearch Id="RegSearch_PIDKEY" Root="HKLM" Key="SOFTWARE\My Company\My App\1.0" Name="SerialNumber" Type="raw" /> </Property> Sascha On Wed, Nov 4, 2009 at 6:31 AM, Tim Musschoot <[email protected]> wrote: > Hello, > > I've found a way of introducing a product serial in the Installer.
