IS 2010 migration: Cryptic 1603 error

[Slander]

Hello,

We have an existing Basic MSI project that I have been tasked with updating to IS 2010 from IS 2009. I imported the old .ism file and Installshield converted it to the new format.

Upon testing this new installer, I keep getting a 1603 error reported and no real obvious errors or hints on where to go from here. I have scoured the internet the past few days looking for hints but have been unsuccessful.

Target machine is running Windows Server 2008. I believe I have narrowed down the Feature in question that is causing the issue however this feature has a lot of functionality built into it. It is making XML changes, making an IIS application pool, and adding some files to the system. I have "Enable 32-bit applications" setting on all application pools I create on this platform. In the Installer GUI, I see Application pools get created then seemingly rolled back immediately afterwards.

The windows installer log has a few instances of "Return Value 3" but no obvious error to report. The first instance of "return value 3" occurs in this context:

InstallShield 17:06:42: Processing XPath '//'

Action ended 17:06:42: InstallFinalize. Return value 3.

We are making some changes to a Tomcat web-app file. Is this XSI namespace issue a red herring or a possible cause for my issue? I am hesitant to say this is the issue because I an not getting Fatal Errors from ISXmlCosting.

Any help would be great, thank you. 😄

So after removing the XML files changes for that particular file, the issue disappeared. :eek:

EDIT: The issue was found to be with the XML file attributes we were adding to these xml files. I deleted the attributes that were left over from IS2009 project and all installed fine.
