Opening the "OutSystemsInstall.log" file you can see that Rich Widgets bootstrap component is failing its installation due to a timeout error:
[21.11.2009 23:33:21] Installing Rich Widgets bootstrap component.
[21.11.2009 23:46:41] Publish Error : Error publishing to 'localhost': The operation has timed out
This happens often when there are antivirus or firewalls that prevent the installer to contact localhost. Do you happen to have one of these running while the installation is going on? If you do, please turn them off while retrying the installation.
Moreover, I see you are installing the a beta version Platform Community Edition 5.0. The final version is out and includes many fixes and enhancements to the first user experience. Download it from http://www.outsystems.com/download and retry your installation.
