Error System.Data.OracleClient requires Oracle client software version 8.1.7 or greater when installs setup

Question

I have made a desktop app Setup that connects with remote Oracle 10g Database. When I install Setup on remote machine and run my application then I get following error:

system.data.oracleclient requires oracle client software version 8.1.7 or greater

It works well on my Development machine.

Answer 1

The error message is pretty self-explanatory: your application needs the Oracle Client installed on the machine it's running on. Your development PC already has it. Make sure your target PC has it, too.

Edit: The System.Data.OracleClient namespace is deprecated. Make sure you use the driver native to your database system, that would be ODP.NET from Oracle.
