Problem connecting to Oracle

[MrBigSpender]

Hello,

Does anybody know about this problem. When I try to connect to my Oracle instance from PL/SQL Developer I receive an error below;

Initialization error
SQL*Net not properly installed

OracleHomeKey: SOFTWARE\ORACLE
OracleHomeDir:

When I connect to Oracle with SQL*Plus everything is OK!

Maybe this is an environment problem. Can you go to Help > About, press the 'Info' button, press the 'Copy all pages' button on this info screen, and paste this text into an e-mail reply?

Was this any resolution to this? We have the same problem here when another client version of Oracle was installed on the desktop. We can no longer connect to any database...?
thanx

Your Primary Oracle Home has probably changed, but is not configured correctly.

Can you also go to Help > About, press the 'Info' button, press the 'Copy all pages' button on this info screen, and paste this text into an e-mail reply?

For Oracle10g you will need PL/SQL Developer 5.1.6 or later. You are using 5.1.3, so you will need to download the 5.1.6 patch.

Hi Marco, I too have PL/SQL 5.1.3 and have recently upgraded to 10g. Can you please point me to where I can download the 5.1.6 patch? I have sent an e-mail to support@allroundautomations.com with the content of the About-->Additional info information.
Thank you.
