The directions state:
- Download the appropriate Instant Client packages for your platform. All installations REQUIRE the Basic package.
- Unzip the packages into a single directory such as "instantclient".
- Set the library loading path in your environment to the directory in Step 2 ("instantclient"). On many UNIX platforms, LD_LIBRARY_PATH is the appropriate environment variable. On Windows, PATH should be used.
- Start your application and enjoy.
Suggest extracting/unzipping into a new directory. They've suggested instantclient, but you can name the directory anything you like. Name it C:\OracleInstantClient\ if you choose.
Then in Step 3, open a Windows Command Prompt. Type:
PATH C:\OracleInstantClient; %PATH%`
That's all there is to it!
