DBDDriver failed to load

Hi,

when we try to open a universe in the universe designer. We got the following error:

Datenbankfehler. Der Datenbankfehlertext lautet: (CS)

"DBDDriver failed to load: C:\Program Files (x86)\Business Objects\Business Objects Enterprise 12.0\win32_x86\dataAccess\connectionServer\dbd_wmssql.dll (Die angegebene Prozedur wurde nicht gefunden.)".(WIS 10901)

We have installed the universe designer on a terminal Server with Windows Server 2008 64 Bit.

What can we do?

Regards

Alexander
