need your help ..
Windows 2008 , I am having a running 11g instance here . Now I installed 12c too in the same box under different home .
Oracle Net Configuration Assistant failed - Failed , otherwise Database install was successful.
upon checking the logs found that , it failed because its not able to launch lsntctl.exe
Now , when I try to start the lsnrct manually , I get this :
C:\Users\hypadmin>lsnrctl start LSNRCTL for 64-bit Windows: Version 12.2.0.1.0 - Production on 14-JUN-2018 11:52 :03

Listener failed to start. See the error message(s) above...
looks like lsnrctl is already in use by 11g.
what I need to do to without causing any harm to 11g.
