Error Windows 64 conecting to oracleDatabase

I’m creating an app to connect to oracle in windows x64.

I have created the connection


I’m receiving the message Some Oracle symbols are not found. Look in the console for more information.

But the connection string is correct.

Can someone help me?

I have instantclient x64 in the oracle folder, created TNSNAMES ans det paths

System.EnvironmentVariable(“ORACLE_HOME”) = “C:\Oracle\instantclient_21_7”

Check your system PATH environment variable to make sure we can find OCI.DLL
