SAP Netweaver'04 EP on SQL server Installation

I am installing SAP Netweaver EP Sneek Preview on MSSQLServer Developer Edition.

According to quick installation guide available with the download files we were at step 4 (Updating SAP EP to SP6).

We received info that EP SP6 patch updation has been aborted with some exception logged in the installation log file just after starting SAP J2EE Engine Deployment.

The GUI error msg is

ERROR 2004-10-19 17:15:42 [iaxxinscbk.cpp:295]

abortInstallation

MUT-02041 SDM call of deploySdaList ends with returncode 4.

Any remedy

Thanks
