Error when connecting to remote SAS server

[EDSHP]

I have a web application which gives an error when it tries to run this code:
SASObjectManager.ObjectFactory sasOman = new SASObjectManager.ObjectFactory();

This is in C#, Visual Studio 2005. The code has worked for years but gives the following error since I moved from Windows XP to Vista (32 bit):

Retrieving the COM class factory for component with CLSID {D6979A24-6B31-11D5-BA37-00C04F81BC00} failed due to the following error: 80040154.

The remote SAS server is 9.1.3.

Please help.

Same error on Dataflux Studio when trying to authenticate on SAS Authentification server from Windows 7 64 bits.

Any idea ?
