Also see: http://blogs.msdn.com/astebner/archive/2004/11/10/255346.aspx. There are several reasons listed here; the most relevant of these are the ones related to .NET Framework. While this error occurs when installing Iron Speed Designer and not the .NET Framework, the reasons are still relevant since both products install assemblies in the Global Assembly Cache (GAC).

If this continues to be a problem, we recommend re-installing the .NET Framework from the following locations. If you are installing .NET Framework 1.1, make sure to install the SP1 patch release.
