Software Deployment

Howdy!

A previous administrator at my job created an Office 2003 installer package using WinInstall LE, and distributed the package via an unknown method leaving no documentation. And now, the installation source has gone MIA and no one currently on board was here when the package was created - including yours truly - so finding the offender has proved

We are now in the midst of a full-on rollout of O2K3 w/patches via GPO distribution, but cannot update installations on client machines that were installed via the above method. The error produced is something along the lines of "WinInstall LE: Evaluation License Expired" (paraphrase). The only working fix that we'e found requires the Windows Installer Clean Up utility to remove the O2K3 installation, after which the GPO method works AOK - but, we'd have to visit 300+ desktops/laptops (either scriptically, or manually) to do so and the only way we know if a WinInstall error will occur is when the user tries to install/update O2K3 (via GPO or Microsoft update). Not very user friendly...

Does anyone know of a registry key, or other method by which we can detect and compile a list of WinInstall O2K3 installations? A registry search for 'wininstall' on an affected system turns up nada. I'd like to tailor a fix for just the WinInstall "infected" systems rather than than a mass uninstall/reinstall...

Thanks in advance for any help!
