# Windows – Oracle program “lsnrctl” is missing after the installation of 32bit Oracle client

installationlisteneroraclewindows-server

I cleaned up my computer for all old Oracle stuff using Uninstall (OUI) and then later used regedit to delete all references to Oracle and then deleted all remains of Oracle directories.

I have HP ProBook with Windows 7 (64-bit) and I want to install a 32 bit Oracle client on it. I need to be connected to an Oracle 11gR2 database on a remote server by OCI, ODBC and OLEDB.

I have done this installation tens of times before, but this time I am stuck.

The command lsnrctl isn't present after the installation, and as expected then, the lsnrctl.exe binary is not present under the Oracle home directory (in BIN) as it should be.

This test shows the frightening situation:

C:\Oracle\product\11.2.0\client_1\BIN>lsnrctl status
'lsnrctl' is not recognized as an internal or external command,
operable program or batch file.


I did the same operations and installation on more time, but with the same result.
Why does this happen and what can I do to straight it out, other than re-installing the whole Windows 7?
