Having installed Wowza server on Windows 7 final x64 bit + java6 + jdk 1.6.0-14 + java FX sdk 1.2 , and Clicking the `Wowza pro startup` icon I get: > Windows cannot find `\bin\java.exe`. Make sure you typed the name correctly and try again. > > Any idea anyone what`s wrong ? > > Thanks ---

Sounds like Java is not installed. Install java. If already installed open a command prompt and type: java -version It should return the Java version number. If the above command does not return a Java version number, then be sure your PATH variable includes the Java bin location. Also be sure the JAVA\_HOME environement variable is pointing to the root directory of your Java installation. Charlie ---

JAVA\_HOME should be set to: ```auto C:\Program Files\Java\jre6 ``` Not: ```auto C:\Program Files\Java\jre6\bin ``` But I think the current problem is something else. It looks like a permission problem. ```auto C:\Program Files\Wowza Media Systems\Wowza Media Server 2 Preview 7\logs\wowzamediaserver_access.log ``` Be sure the user you are logged in as has full file permissions to this directory and all files as sub-folders: ```auto C:\Program Files\Wowza Media Systems\Wowza Media Server 2 Preview 7 ``` Charlie ---

I don’t think it is necessary to run Wowza, but to make the java -version command work from anywhere you do have to add path to java.exe in your Path variable, something like this: > ;C:\Program Files\Java\jdk1.6.0\_16\bin On XP you edit path by right clicking My Computer → Properties → Advanced Tab → Environment Variables Button. Then scroll down in the list of System Variables to Path, and click edit, then add correct path to the end of the with a semi-colon separator. And I think you have to reboot. That makes the java command available from anywhere. or you can do it like this: > cd C:\Program Files\Java\jdk1.6.0\_16\bin > > java -version Richard ---

See what you get in cmd window with these commands: echo %WMSAPP\_HOME% echo %WMSCONFIG\_HOME% Should be path to Wowza install, and should not end with “/” Richard ---

Thanks for responding Charlie. You solved my problem , but I am still not sure about one issue : run\>java -version gave: > Windows cannot find java My JAVA\_HOME held the path to jdk 1.60\_14 so I changed it to the jre6. Now the Wowza server does startup with no issues, and [http://localhost:1935](http://localhost:1935) is all good. But run\>java -version still gives the same message about not finding Java. could this be a windows 7 issue, that it needs some different command to locate the Java ? ( also: I have no clue where to find the `path variable` if this is still relevant at all) Thanks a lot for your help. ---

I corrected JAVA\_HOME as c.\Program Files\Java\jre6 Checked if the user has full rights. They are ok. I get : Configure logging: file:///C:/Program Files/Wowza Media Systems/Wowza Media Serv er 2 Preview 7/conf/log4j.properties INFO server server-start 2.0.0-preview7 build21940 - ERROR server comment - server core failure: java.lang.NullPointerException java.lang.NullPointerException at com.wowza.wms.server.Server.startServer(Unknown Source) at com.wowza.wms.server.Server.start(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.wowza.wms.bootstrap.Bootstrap.startServer(Bootstrap.java:248) at com.wowza.wms.bootstrap.Bootstrap.main(Bootstrap.java:47) I will try with Windows 2008 and see whta happnes there… Regards Gokhan
