Dear Peter.
I get the same error. As I read in the SAP Note RTC of ABAP development tools for SAP NetWeaver 2.7, note 1856574, only versions 3.7.x (Indigo) and 4.2.x (Juno) are supported. SAP HANA Studio rev. 72 is based on Eclipse Platform 4.3.1.
Just, download Revision 69 for SAP HANA STUDIO 1.00 (02.2014) instead of rev. 72, and install it on C:/ or other unit. (Do not use C:/Program files/ directory. Here you have an explanation: 1828400 - SAPUI5 tools disappeared after updating HANA Studio).
Then, follow steps of attachment to note 1950493.
Best regards,
Nacho
