What steps did you follow?
You should simply be able to enter the ip address of the studio appliance in your browser's navigation bar.
Did you ensure connectivity between whatever comp. you are using and the appliance?
The browser's debug tools might give you a better idea.
If you are using Chrome or Safari for example you can hit F12, select the Network tab and refresh the page. If there are connectivity problems you will them there.
1. Installation is just the installation of the OVF.
2. I can telnet to the machine ok and If I add hello.html to /opt/vmware/www, I can access it via the browser.
3. I see that the http is redirecting to port 5480 (and https). but if my hello.html come up, the network must be ok.
You shouldn't change anything.
If you installed the appliance successfully then entering the ip address in your browser is enough.
