Microsoft Odbc For Oracle

I have an old 32-bit software program that connects to an Oracle database but only works with the Microsoft ODBC driver for Oracle. It does not work with the more up-to-date native Oracle ODBC driver.

Instant Client Downloads for Microsoft Windows (x64) 64-bit See the Instant Client Home Page for more information about Instant Client. The installation instructions are at the foot of the page. Oracle Client-to-Oracle Database version interoperability is detailed in Doc ID 207303.1.For example, applications using Oracle Call Interface 19 can connect to Oracle Database 11.2 or later. Oracle 12c client or the Oracle 12c ODBC Driver (or both). Some report writing tools, such as SAS or Crystal Reports, can use either the Oracle client to access the database directly in its own language, or use the Oracle 12c ODBC Driver to access the database indirectly using ODBC as a type of middle-layer “translator”. For example, Microsoft.

I have installed the Oracle Instant Client (32-bit and 64-bit versions on my 64-bit Win 7 PC), each into different ORACLE_HOME directories.

However when I try to connect via ODBC with Microsoft's driver, I get the error:

The Oracle(tm) client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3 (or greater) client software installation.

You will be unable to use this driver until these components have been installed.

I can connect to the database fine with Oracle's ODBC driver so the install seems fine, but alas this program will only work with Microsoft's ODBC driver.

Since the Microsoft ODBC driver is apparently unable to find the Oracle Instant Client install, how should I tell it where to look?

Technology used: Windows 7, UFT 32 bit, Data Source ODBC pointing out to 32 bit C:WindowsSystem32odbcad32.exe, Oracle client with both versions installed 32 bit and 64 bit.

What worked for me:

1. Start -> search for “Edit the system environment variables”
2. System Variables -> Edit Path

3. Place the path for Oracle client 32 bit in front of the path for Oracle Client 64 bit. Ex:

Turns out this is quite simple. You have to set the PATH environment variable to point to the ORACLE_HOME that you want to use.

For me, I edited the PATH to add ;C:oracleinstantclient32_12_1 on the end and it worked perfectly, no restart needed.

For clarification, the C:oracleinstantclient32_12_1 directory I specified contains files like oci.dll and ociw32.dll and belonged to the 32-bit Instant Client install. I guess it doesn't matter for 64-bit, since there is no Microsoft ODBC 64-bit client.
