This error normally occurs if you have installed the .NET Framework 2.0 Beta, or Visual Studio 2005 Beta (which installs the Framework 2.0 Beta) before installing NI-VISA 3.2 with COM Support enabled.
Look
here for handle this issue.
I´m not sure but I think this is fixed for VISA 3.3. Try to install
VISA 3.3 separetley after LV installation.<
