Check the Oracle client software, do you have the 64-bit version installed?

Secondly, check the NTFS permissions on the Oracle folder. Make sure your user can read the tnsnames.ora file

Hello Kristof,

yes indeed, i had 64-bit version already installed, i uninstall it and installa the 23-bit version and it works.

Thank you.
Best Regards.
