I don't believe Oracle uses the Registry on Windows. There should be a tnsnames.ora file in <OracleHome>/Network/Admin. See if you have an environment variable of ORACLE_HOME (You may also have TWO_TASK and ORACLE_SID defined). Also make sure which Oracle client you have installed. ARS 7.1 uses the Oracle 10g (32 bit) client Fred

The Oracle services are running, I can log in and navigate in the browser-based Administration, so I am pretty sure that the DB is up. However, the AR System installer seems to think otherwise. I get this error message when specifying the DB information: "Could not connect to the database. Verify the selected Database Server is running". There's only one instance of the DB running, and the SID is specified as "XE" both in the installer and in the tnsnames.ora file. I got that value from the Registry. So what am I missing here?
