STAAD Directory

Hi.

I am using STAADPro v8i6 (latest version) and Tekla 2016 with x64 PC.

Does anybody know where is the location of these files staadRead.dll and staadread.tbl?

I am following a procedure from this thread in Tekla

https://forum.tekla.com/index.php?/topic/14272-issue-in-import-from-staadpro-to-tekla/?hl=%2Bconversion+%2Bfile#entry61357

but I can't seem to locate files.

Do I need to install extensions first? or plug-ins from openSTAAD?

Thanks
