Windows Installer Error Messages 2503 & 2502

When using certain Wise Package Studio tools, sometimes the resulting MSI file may not have a product name. When you try to install the resulting MSI file, you get a Windows Installer Error Message 2503 or 2502 and the MSI does not install.

To correct this problem, make sure a product name has been set in the MSI file.

I'm unsure if these errors also display for other missing product details.
