Hey all...

I'm trying to install the GPS software for the WWAN card I installed in my T400. I downloaded the GPS package from the Lenovo website, but whenever I try to run the installed, I get:

Error 1720. There is a problem with this Windows Installer package. A script required for this install to complete could not be fun. Contact your support personnel or package vendor. Custom action _CA_IS_DLLFound script error -2147024770, : Line ...

... anyone see this, and find a way around it? I tried installing via System Update, but System Update fails consistently every time I try to use it, with a .NET error (and I've also completely uninstalled and reinstalled .NET, AND System Update).

Well, I managed to get it to install; I had to run the installer, find where it had placed the Microsoft Installer .MSI file, edit the file with "Orca" (an installer debugging tool), and, eventually, removed the problematic scripting errors... lucky for me, they only existed in 2 places - one where it checked for the existence of the GPS device DLL's, and the other where it cleaned up old shortcuts after the install.

The guy at Lenovo -- when I called him -- was able to run the installer on his desktop (tho' of course it didn't find the GPS device). I can't imagine what's wrong with my Windows installation that could cause this odd problem; perhaps some strange registry state, or the wrong version of some DLL's that the installer depends upon (possibly some VBScript-related stuff).

Very very weird... unless someone knows why this happens, it remains a mystery.

In any case, if anyone else ever has this problem, try "Orca"... really useful!
