Autodesk Revit 2012 and Configuration Manager 2007: Win7 vs XP

While packaging Autodesk Revit 2012 Architecture Suite for mass deployment (via Microsoft System Center Configuration Manager 2007 R3), I encountered a problem where Windows 7 clients installed just fine, but Windows XP SP3 clients did not.  The error was 1603 or 1619, but the client log did not indicate any more specifics.  I ran the installation  (deployment) manually (interactively) and it worked fine on both platforms, but through Configuration Manager 2007 R3 it would not successfully install on Windows XP SP3 clients.  At all.  Ever.

Until...

It's an old trick that sometimes works, and in this case it did:

Within the Package, under the Program properties settings, on the Environment tab, check the option...

"Allow users to interact with this program"

It now installs on Windows XP SP3 clients as well as Windows 7 clients.
