Hi Asiya,
The contents of your Ferret-7.5.0-RHEL6-64 directory are exactly the extracted contents of the fer_environment.tar.gz and fer_executable.tar.gz files. So you do not need to do step 1 of the Finstall. Only do step 2 of the Finstall. (I see I forgot to include that information for this release; it is now added.)
Thank you,
Karl
