JBoss EAP Installer hangs on Windows

Issue

• I downloaded "Red Hat JBoss Enterprise Application Platform 6.1.0 Installer" from the CSP and attempted an install of JBOSS EAP from the console on my Windows 7 platform. All seemed to work until the install got to "Starting process Unpacking (2/2)" at which point it hangs until the process is killed (I let it run overnight to no avail). Can you give me any guidance as to why this may be failing?
• The jboss installer (jboss-eap-6.1.0-installer.jar) appears to stall on multiple systems during the unpacking process (on 2/3). The process has been running for 24 hours now.
• Using the Windows installer, the installation process gets hung, frozen, stuck, wedged, locked up, freezes in the unpacking phase and never comes back
