Can not set SNC for ABAP eclipse (SNC library missing)

Hello together,

I have newly installed ABAP Trial 7.03 and the ABAP Development Tools for Eclipse. The installation guide requires setting SNC for eclipse. This is giving me the following error. From eclipse I receive a similar error message: can not connect as the SNC library is missing.

It seems there is a library missing with my installation. Anybody else occured that before? Many thanks for solutions in advance.
