Errors in Eclipse - while installing new software.

Hi,

I get following error while trying to install new software. I tried both Kepeler Service Release 2 and Luna versions and always get similar errors. Any idea what is missing?

Operation details

  Cannot complete the install because one or more required items could not be found.

    Software currently installed: ABAP Development Tools for SAP HANA (Developer Edition) 2.36.1 (com.sap.adt.tools.hana.devedition.feature.group 2.36.1)

    Missing requirement: ABAP Development Tools Foundation 2.36.2 (com.sap.adt.tools.feature.group 2.36.2) requires 'org.eclipse.mylyn.context_feature.feature.group [3.9.0,4.0.0)' but it could not be found

    Cannot satisfy dependency:

      From: ABAP Development Tools for SAP HANA (Developer Edition) 2.36.1 (com.sap.adt.tools.hana.devedition.feature.group 2.36.1)

      To: com.sap.adt.tools.hana.feature.group [2.36.1]
