'OraOLEDB.Oracle.1' is not registered on local machine

Hi all of you,

Primary platform is Framework 2.0 running over XP.

I've got an issue with a SSIS package which uses Oracle Provider for OleDB:

Test connection failed because of an error in initializing provider 'OraOLEDB.Oracle.1' is not registered on local machine

Nevertheless, MS Ole DB Provider for Oracle works fine. Let me know where am I failing.

Thanks in advance,
