maxdb studio not connecting to database

Hi MAXDB experts,

I have installed MaxDB_7.9_RDBMS___SP8_Build_21 for Content Server.

Then I installed  maxdb-studio-desktop-win-64bit-x86_64-7_9_08_31

to connect the database but it is not connecting.

i tried connecting through dbmcli, database is connecting perfectly.

The OS used is windows 2012 -- Maxdb Studio supports win2012 server?.

Can anybody help me here?

Regards,

Suresh Daniel.
