Hello Dan, thanks for the reply.
But the case is that this tool requires ArcInfo Workstation installed as shown below and i can't find this ArcInfo Workstation anywhere and was not lucky enough to find any alternative for the conversion process as well.
Check your 'My Esri', go to your Organizations, then to Downloads. If your organization has it, it will be listed there. If not, you will have to locate a machine that has it.
I did check My ESRI first thing with no joy, it seems it has been discontinued but there should be somewhere else where this ArcInfo Workstation exists but i do not have any clue
Just to add to this thread workstation does still run, see ArcInfo Workstation Guidance -- though of course no tech support of bug fixes. If you need workstation I would follow up with through your customer service rep.
