That error happens when the server isn't started in five minutes. To get around this, you can try starting it using the command line. To do this, open the windows command line prompt, navigate to the root of your installation,

C:\Program Files\OpenGeo\OpenGeo Suite\

and start the service

opengeo-suite start

Hopefully, it would work this time. Good luck!
