No, you can't. Only a transform can be applied at the right time to change those values.
Furthermore, I would not recommend using Script for CustomActions ever. -----Original Message----- From: Dmitry Briliuk [mailto:[EMAIL PROTECTED] Sent: Monday, September 25, 2006 12:29 PM To: Rob Mensching Cc: 'Mike Dimmick'; wix-users@lists.sourceforge.net Subject: Re[2]: [WiX-users] install multiple instances of app? Hello Rob, Thanks Also, is it possible to change ProductCode, ProductName and PackageId from inside msi by calling script? So, the msi will detect existing product by comparing it with new guid, generated by script? I have tried something like this: Session.Property["ProductName"] = "new product name" Session.Property["ProductCode"] = new_guid but it does not affect on installed product properties, however in logs, after PublishProperties it shows values assigned by script.
