[ferret_users] Ferret installation error

[abs15ms027 <abs15ms027@xxxxxxxxxxxxxx>]

Hello,
 
Recently I was trying to install ferret and I downloaded these two zip 
files for the same purpose.
 
1)Ferret-7.5.0-RHEL6-64.tar.gz
2)Ferret-7.5.0.tar.gz
 
After this step --%tar xzf $GET_LOCATION/ferret-7.4-RHEL7-64.tar.gz--,
 
If I do ls Ferret-7.5.0-RHEL6-64, I am supposed to get
 
bin/
contrib/
examples/
ext_func/
fer_environment.tar.gz
fer_executables.tar.gz
go/
ppl/
 
 
But I don't have 'fer_environment.tar.gz' and 'fer_executables.tar.gz' 
listed in my Ferret-7.5.0-RHEL6-64 directory.
 
 
So, When Finstall prompts me for the directory I installed the Ferret 
support files if I give complete path to Ferret-7.5.0-RHEL6-64, I get 
this message--
 
'fer_executables.tar.gz' is not in 
/home/psanyal/15ms027/new_ferret/Ferret-7.5.0-RHEL6-64
 
How to solve this issue?
 
Thanking you in anticipation
