Installation upgrade/maint mode issue after Installshield 2010 -> 2012

Hi all,

We've been working with IS 2010 Pro for quite some time. We do our new builds, build the installations, etc. When you run the new installation on a server that already has the software installed, you get the nice "going to upgrade from version 1 to version 2..." dialog box. Been working fine for years.

I've done the following, and the maint/mode upgrade is broken - it fails to upgrade any files in the installation folder (but it does other tasks, like running our SQL scripts):
- Upgraded to 2012 Premier
- Added a language
- Rebuilt our installation

Fresh installation works great, puts the right files down.

Any tips while we troubleshoot?

Thanks,

Chris
