It should pick up your Oracle Instant Client if that's the only client you have. It should look something like the following screenshot: This makes it easy for Toad to find if you have a lot of entries. Then move the entry to the top of the list by clicking on “Move Up”. In my case that directory was C:\instantclient_19_6. Click on New, and create an entry with the directory where you extract the zip file from step 1.In the user variables, select “Path” then click on Edit. We’ll focus on the top half user variables. Once you get to the Environment Variables, the top half of the window are variable settings just for your Windows account and the bottom half is for everyone who uses this computer, which you may or may not have access to change.Then select the Advanced tab, then Environment Variables: You can edit system environment variables for all users on the computer if you have administrator permissions, or you can just edit environment variables for your current user login account.įor older Windows, you can right click on My Computer (or This PC), and select Properties: Go into Windows Start Menu or Windows Settings and search for “Environment Variables.” You can use the quick search like shown in my first screenshot.

There are several ways to go about this next step and it depends on your version of Windows too.Extract the contents of the zip file to a folder, such as C:\instantclient_19_6.The latest version is 19.6.0 and basic light package has all you need to connect to a database and run some queries in about a 40 megabyte zip file.If you need a 32-bit client, then download that and install 32-bit version of Toad for Oracle. If you're going to be using a 64-bit version of Toad for Oracle, then you should download and install the 64-bit version of the Instant Client.
