TNS Listener Crashes with error

I got the follwoing error in TNS Listner after installing Oracle application server 10g.

lsnrctl Message 1073 not found; No message file for product=NETWORK, facility=TNS

and

Windows No such file or directory message.

To see this error use Start>Run and type cmd and press enter
then type lsnrctl status and press enter.

The issue is with the ORACLE_HOME envirnment variable which got change after installing the application server.

To fix this change the ORACLE_HOME to C:\oraclexe\app\oracle\product\10.2.0\server in my case. This should be done in My Computer>Properties>Advanced Tab>Envirnoment Variables.

Please check the registry key
ORACLE_HOME
in
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Session Manager\Environment

which should be the same as above.
