Hi @sprasad1, sorry for the runaround. Could you please explain exactly which SDK is being used (a link would be ideal) as Tobii have several different API and indeed the only one that is supported for use with the ET5 is the Stream Engine which is 64bit only… perhaps your client has a 4C?
We have never produced any driver or software for the ET5 that is 32bit, so I think perhaps there is some points to clarify. Thanks.
