As you are an SAP employee using SAP internal builds of the software, I suggest you post these problems as an internal support ticket rather than on the on the public SCN forums.
Also 32-bit Studio/Client has nothing to do with OData support. I have no idea what you mean by that. What is missing from 32-bit client is REGI - which is a tool needed for the check in/out from the HANA Repository. Therefore for usage of the HANA Studio Development Perspective we currently require either the Linux or Windows 64bit version of the HANA client.
