This problem is known to occur on systems that have Microsoft .NET Framework version 3.5 installed. Microsoft .NET Framework 3.5 includes new features that Web Builder version 6.5 does not support.
Solution
To resolve this issue, upgrade to Verastream Host Integrator version 6.6, which works with .NET Framework version 3.5 (and Microsoft Visual Studio 2008). For more information on version 6.6 features and fixes, and how to obtain this new release, see Technical Note 10080.
This problem does not occur when only .NET Framework versions 2.0 and/or 3.0 are installed, so if you cannot upgrade to version 6.6, install Host Integrator Development Kit 6.5 on a system without .NET Framework 3.5.
