I need to test iSpring SDK in our platform of e-learning. I referenced the iSpring 5.0 type library in a project. Net (console application, VS2008, framework 3.5) and I get an error during execution.

Here's the code:

PresentationConverter converter = new PresentationConverter();
   converter.Settings.Navigation.HyperlinksTarget = "_blank";
   converter.GenerateSolidPresentation("M:\\IspringTest\\test.swf", "", "");
   catch (Exception)

Here is the error:
Impossible d'effectuer un cast d'un objet COM de type 'iSpring.PresentationConverterClass' en type d'interface 'iSpring._PresentationConverter'. Cette opération a échoué, car l'appel QueryInterface sur le composant COM pour l'interface avec l'IID '{D408B878-2162-4F12-A1FC-DF2CCC99D2EC}' a échoué en raison de l'erreur suivante : No such interface supported (Exception de HRESULT : 0x80004002 (E_NOINTERFACE)).

Do you know why this error?

thank you for all information

This issue has been fixed in the most recent build of iSpring SDK.
Please uninstall your current version of the SDK and install the latest version from our web site
