Receiving an installation error as soon as Visual Studio 2008 starts to install Microsoft Visual Studio Web Authoring Components?
If you're lucky, you just need to uninstall "Microsoft Office InfoPath MUI (language) 2007 (Beta)"
To uninstall:
msiexec /x {30120000-0044-0C0A-0000-0000000FF1CE}
In our case, this package was installed by the Microsoft Office Enterprise 2007 *SPANISH* installer, which includes a beta version of it:
"Microsoft Office InfoPath MUI (Spanish) 2007 (Beta)"
In other cases, you may need to uninstall other Office 2007 components, specially the MUI packages.
