OUI May Deinstall Unintended Files

One of my co-workers encountered the following issue earlier today:

This is just a heads up that Oracle OUI may deinstall unintended files. I used 11.1.0.7 OUI to deinstall Oracle 10.1 & 10.2 client and server installations today, and soon after these errors appeared –
ORA-12154: TNS:could not resolve the connect identifier specified

The deinstaller removed the tnsnames.ora, sqlnet.ora & listener.ora files in the active $ORACLE_HOME/network/admin directory even though TNS_ADMIN was set correctly. The missing files had to be extracted from the tar backup and restored to the correct location. I did not find this specific issue in My Oracle Support, but did find some similar problems reported for Oracle 11.2. Support request was opened.

Thx
