cannot launch PL/SQL dev ... ORA 12154...Could not resolve TNS name

[Jeevan]

Hi,

PL/ SQL dev has been my preferred tool, when working with Oracle.

On my new box, I installed PL/SQL developer 7.1.5.1398
but cannot log into my database with it.

It gives me a ORA 12154 : TNS Could not resolve name, error
But on the same box,
I can use (SQL net) SQL PlusW, to connect to the same database.

Also, in the logon dialog, the database dropdown combo, is properly populated with entries defined in the TNSNames.ora

Also, after PL/SQL Dev, has launched (but not connected), I puuled up its about box, and other info (like TNS Names), which is perfect.

So where could the problem be?

Is there anyway to diagnose?

found the culprit....

it was due to "oracle bug 3807408" as PL/SQL dev was installed under
c:\Program Files (x86)\PLSQL....

I moved it to another folder without the "(x86)" and it worked.
