I remember looking at this many years ago and the observation and consensus was that you couldn't change it. That MSI read it in when it initialized and that was that. Maybe it does warrant reexamining as it'd be useful in multiple instance scenarios (think named instances ).
I know the MSDN help topic (http://msdn.microsoft.com/en-us/library/windows/desktop/aa370857(v=vs.85).a spx) says: "This property can be changed by a transform." Knowing how horribly cryptic the SDK is, the translation has always been "can be only changed" as it would otherwise be pointless to mention that something can be changed by a transform. Because, well, duh, nearly anything can be changed by a transform. ---------------------------------------- From: "Matt O'Connell" <techsupport...@gmail.com> Sent: Friday, August 31, 2012 4:47 AM To: chr...@iswix.com, "General discussion for Windows Installer XML toolset." <wix-users@lists.sourceforge.net> Subject: Re: [WiX-users] Changing product name at install time That's not what I've found. I've got a custom action running which changes our ProductName at install time in WiX 3.5. It is one our first actions in our InstallExecuteSequence and seems to work. All the Actions before it need to not reference [ProductName] or else get the 'wrong' result. Can you think of something wrong with this or is this not good practice for some reason?
