A folder listing really doesn't tell us anything about the environment.  It also doesn't look like the installation folder.


Assuming you ran a client install, what was the installation folder you gave it?
This can also be found in the registry under ORACLE.

Look for ORACLE_HOME.

After you installed the client, did you configure the tnsnames.ora file using an assistant or manually?

pl/sql developer can only use a 32-bit client.  

Is your 12c client 64-bit?


also,  ver 7 is pretty old,  I wouldn't be surprised if it couldn't recognize a lot of stuff in 12c

I copied my tnsnames.ora file from another laptop.   Tnsping commands work properly.

My windows is 64-bit, that is why i installed 12c cliente 64-bit.

>>>My windows is 64-bit, that is why i installed 12c cliente 64-bit.

that's the problem.


you can install a 32bit client on 64 bit windows and use it for pl/sql developer.
but, as I noted earlier, version 7 of the IDE was written long before 12c ever came around so it's possible you might still have some compatibility issues.
