[xwiki-users] Installation Issue

I am unable to complete the installation using either the Windows .exe or the jar file. I get to the unpacking step and the 'next arrow' doesn't do anything. I am running Windows 7 64-bit. I am running as administrator. In the command window I get: Microsoft Windows [Version 6.1.7600] Copyright (c) 2009 Microsoft Corporation.
