For French-challenged people, this message in English means "The
requested service provider could not be loaded or initialized."

Does this happen in "emacs -Q"?  Do you have an emacs-server running?

If "emacs -Q" shows the same problem, I'd suggest using SysInternals
tools to find what exactly happens and why.  ProcessExplorer and
ProcessMonitor come to mind.
