Windows XP Pro
Instant client win32 18.104.22.168.0
Instant Client installation directory in PATH
tnsnames.ora and sqlnet.ora in TNS_ADMIN path.
No Oracle Client or any other Oracle software installed on the machine.
I cannot make the configuration above work. Toad home list shows the Instant Client directory in red and the message "This Oracle home is invalid".
Is this configuration supported? Do I need to install the Oracle Client software? (it is not necessary with Oracle SQLDeveloper)
