I have currently installed Wowza Media Server, on my linux environment,

I have also successfully installed JDK 1.6

here is my linux information:

Linux [isimiyap.com](http://isimiyap.com) 2.6.9-023stab046.2-enterprise #1 SMP Mon Dec 10 15:22:33 MSK 2007 i686 i686 i386 GNU/Linux

after reading your manual, looking for the serial number, server.license I cannot locate it. specially under

usr/local/WowzaMediaServerPro/conf

Other path also proved futile.

attached are the following logs for your analysis

I will be grateful for your assistance given.

If you don’t have a serial number, you can obtain the one here:

[https://www.wowza.com/store.html](https://www.wowza.com/store.html)

You must start the server standalone and it will prompt you for the serial number:

```auto
cd /usr/local/WowzaMediaServerPro/bin
./startup.sh

```

It will then ask you to enter the serial number.
