Yes sir. Contacted sales, returned my V5 license, picking up the V6 one now.
Where on the web site can you get the V5 legacy licenses?
I found it - under Support
I did have the wrong version I contacted sales I was able to replace my license to Windows Rhino version 6 which enabled me to get the Mac legacy version 5.3 license Sales department was great to deal with and sent me the proper links made it easy, thanks to everyone posting to this post I probably would have missed my mistake, cheers
