I can able to install Wowza Streaming Engine in Mac OS X version 10.9 . During installation, it asks username and password and trial license key. So I can able to install successfully and can able to open the login page with these credentials. But If I try to install Wowza Streaming Engine in Mac OS X version 10.7.5, during installation, it is not asking for username ,password and trial license key. But installation finishes. So in this case , what could be the default username and password to open the login page. i.e. http://localhost:8088/enginemanager/login.htm . In few other versions, not even installing. The error comes like "Installation failed". Please suggest me.
Thanks in advance.
