Oracle - Instant Client

Question

I'm trying to install the Oracle Instant Client and ODBC drivers on a 64 bit, Windows 7 machine.

I have downloaded BOTH

• Instant Client Package - Basic
• Instant Client Package - ODBC

I had put both sets of files in the same directory:

C:\Oracle\instantclient_11_2

I set both the ORACLE_HOME and TNS_ADMIN environment variables to the same directory:

C:\Oracle\instantclient_11_2

Finally, I am trying to execute the "odbc_install.exe" file as an administrator.

ERROR: Oracle ODBC driver with the same name already exists

The one thing I did BEFORE any of this was to install and later uninstall the OracleXEClient.exe file.

Not sure how to proceed???

Answer 1

Open Command Prompt as an Administrator and the run odbc_install.exe from there.
