Error while downloading agentDownload.vbs for Oracle 11g DB on Windows (11g grid control 11.1.0.1.0)

Hi everyone,
I already have a grid control 11g (11.1.0.1.0) running on Oracle Linux 64 bit.
Repository database is using the 11.2.0.2.
Weblogic server is using 10.3.2.

Now, I'm trying to setup a management agent in a windows machine.
I was stuck at the step on downloading the agentDownload.vbs from the grid control.

This is what I got:

D:\swinstall\agent>wget http:<font color="#000000">//hostname.domain:4889/agent_download/11.1.0.1.0/windows_x64/agentDownload.vbs</font>
--17:41:12--  http:<font color="#000000">//hostname.domain:4889/agent_download/11.1.0.1.0/windows_x64/agentDownload.vbs</font>
           => `agentDownload.vbs<font color="navy">'</font>
