TurboTax Incorporated trouble netfiling

When I try to file electronically, I get an error popup that says:

"Unable to cast COM object of type 'System._ComObject' to interface type 'ProFileAdapter.Variant.IGPVariantAdapter'. This operation failed because the QueryInterface call on the COM component fo the interface with IID '{...}' failed due to the following error: Error loading type library/DLL. (Exception from HRESULT: ... (TYPE_E_CANTLOADLIBRARY)

I'm on Windows 7
