UI Registration urgent question

Hi all,

according to SAP, any addon registration must call functions in a dll called "<b>sboaddonreg.dll</b>".

This has always worked so far.

But lately, for some reason this dll is missing after a new installation of the SBO client. UIAPI and DIAPI have been installed on client as well.

Does anyone know which of the above should / does install the "<b>sboaddonreg.dll</b>", so I can check what went wrong during the installation?

Thanks a million, Lutz Morrien
