Installation coucbase on windows

I started to install couchbase on Windows 7 32 bits by executing couchbase-server-enterprise_2.5.1_x86.setup.exe. At the end of the wizard installation, the window said nothing, that it is finished for example, and when i try to connect to the couchbase console, through http://localhost:8091/ i get the message this page can’t opened itself. Do you know how i can finish the installation ?
