ecos-install.tcl fails (Ubuntu)

[Bob Brusa <bob dot brusa at gmail dot com>]

Hi,
following insurmountable problems with cygwin and ecos on my windows 
7-64 PC, I installed VMware Workstation and created an Ubuntu system 
using Ubuntu 12.04 LTS (File: ubuntu-12.04.3-desktop-amd64.iso)

Q1: My PC uses an Intel-processor and hence the term amd64 in the above 
file irritates me. Is this the correct version or do I have to go for 
the 32-bit version - despite using a 64-processor?

Then I tried to install ecos. The command

sh ecos-install.tcl

however fails with the message:
====================================================

Giving up.

---------------------------------------------------------
Download failed. Perhaps you need to set a proxy to
connect via a firewall?

Configure a proxy? [Y/n]
=============================================================
My windows firewall is disabled and I also disabled the firewall of 
Defender pro --> Same result
Q2: Has somebody a hint what could be done to overcome this problem?
Regards - Bob
