I'm glad that fixed your problem. You may want to start reading the documentation at
https://openacs.org/doc/openacs-5-1/ if you haven't.
You could put a test page in C:\OpenACS\openacs-5.1.5\www\ and see if you can load it in your browser.
OpenACS includes many packages that offer functionality such as forums or bug tracking. You first "install" the packages that you want. This creates the database tables they need, etc. You can use the "site map" administration tool to see how various URLs map to installed packages. Look around http://192.168.77.9/acs-admin/ and http://192.168.77.9/admin/
