Installation issues with Microsoft .NET Framework (error: 1603)

We've received a few support calls of late where Microsoft .NET Framework has interfered with the installation of Autodesk products.

e.g. "2013/4/4:16:35:22 PC Install .NET Framework Runtime 4.0 Failed Installation aborted, Result=1603"

This can be .NET 4.5 or previous versions and may be related to corruption.  Corrupted frameworks will render you unable to uninstall them from Add/Remove Programs.

This tool over at Download Crew will enable you to get rid of the framework of your choosing, and then allow you to proceed with your product installation.
