Re: [WiX-users] Upgraded merge modules

[Rob Mensching]

Ahh, well, you should probably file a bug against InstallShield.  They aren’t doing the right thing according to the MSI SDK (unless I’m misunderstanding the SDK, which is possible... I did write that spec a very long time ago… when  I was an intern <smile/>).   From: Antony Walmsley [mailto:[EMAIL PROTECTED] Sent: Thursday, October 05, 2006 9:26 AM To: Rob Mensching Cc: wix-users@lists.sourceforge.net Subject: Re: [WiX-users] Upgraded merge modules   Thanks Rob. This issue has come about because our product groups use InstallShield to incorporate the merge modules into their installers. It seems that InstallShield uses the module GUID and locale to decide whether 2 merge modules are the same. These values are the same in both the new and old merge modules so when IS brings up the list of available modules it only shows the latest version even if the version number and file name (and folder location) are different. Since they still want to release installers for older versions, we will need to change the module GUID so that both versions appear in InstallShield's list of modules.
