I feel the above error might be because of the getInstalledReleasesWin()  is of  wrong version format.Can any one tell me wat is the right version to be used
Kindly help me in resolving this issue..

Answer 1

Hi,
the following eror is the main reason why your installation won't continue:
MaxDB sdbuninst: found instance J2E
MaxDB sdbuninst: cannot remove package "Database Kernel": first you have to remove all instances
That means you already/still have an exisisting MaxDB instance on your laptop, which has not been removed totally yet.
If you have access to OSS, please take a look at note 599129:
You must stop and delete all database instances that were installed with
the software package to be deleted.
1.  Identify the database instances (there is usually only one database
    instance).
    Use the following command:
    dbmcli db_enum
2.  Stop all database instances for which the <dependent_path> directory
    to be deleted is displayed using the following command:
    dbmcli -d <database_name> -u <dbm_user>,<password> db_offline
3.  Delete the database instances using the following command:
    dbmcli -d <database_name> -u <dbm_user>,<password> db_drop
4. If you are sure no other MaxDB instances should exist on the machine <b>and</b> no other MaxDB software packages should exist either, then you'd have to perform a complete uninstallation of the SAP DB or MaxDB software.
To uninstall the complete SAP DB or MaxDB software, enter the
following command:
   sdbuninst -all
5. You should be able to (re)install your sneak preview SAP NW2004S afterwards.
