trouble downloading postgres 9.4 for RHEL 6.x

Several weeks ago, I successfully
downloaded postgresql-9.4.4-3-linux-x64.run on a Linux server.

Today, I attempted to download from the site. I notice 9.5 is there, but
getting lots of errors:

1) when downloading and running latest

rchive: /home/apatnaik/Downloads/postgresql-9.4.5-1-windows-x64.exe
[/home/apatnaik/Downloads/postgresql-9.4.5-1-windows-x64.exe]
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
zipinfo: cannot find zipfile directory in one of
/home/apatnaik/Downloads/postgresql-9.4.5-1-windows-x64.exe or
/home/apatnaik/Downloads/postgresql-9.4.5-1-windows-x64.exe.zip,
and cannot find
/home/apatnaik/Downloads/postgresql-9.4.5-1-windows-x64.exe.ZIP, period.

2) Then I tried to scp from the other machine and changed permissions to
777 and used sudo to execute the file but get this:

bash-4.1$ chmod 777 postgresql-9.4.4-3-linux-x64.run
bash-4.1$ sudo ./postgresql-9.4.4-3-linux-x64.run
Installer payload initialization failed. This is likely due to an
incomplete or corrupt downloaded file.

What is the recommended 9.4 version to download from and the steps?

I want to use the graphical installer since I used it last time.

Thanks a lot!!
