Optos discontinued all R&D works with standalone model of OCT in 2013.
As a result of end of life Windows XP, OCT software version 1.90 for Windows 7 was released in 2015. This version of OCT software is only for HP Z400 and DTX workstations.
We still provide support for OCT units, however there are no plans for future development.
I think that the answer to Roland should come from product management.
