i´ve got one system in our lab where Win8 x64 is installed, Rhino 4 without service release and Rhino5 with SR5 is installed (x86 and x64). If i try to install SR9 for Rhino 4, i´m facing an error message that the version i like to install is the same as the version which is installed. The Rhino 4 install seems from Feb.2007, Once i open Rhino4 it reminds me that a new service release is available.
Both versions are Lab licenses. Any clues how to update RH4 to SR9 ?
