If you intend to co-locate optional Oracle configuration files such as tnsnames.ora, sqlnet.ora, ldap.ora, or oraaccess.xml with Instant Client, then create a subdirectory such as C:\oracle\instantclient_19_3\network\admin.Instant Client 12.1 requires the Visual Studio 2010 redistributable. Instant Client 18 and 12.2 require the Visual Studio 2013 redistributable. Instant Client 19 requires the Visual Studio 2017 redistributable. Download and install the correct Visual Studio Redistributable from Microsoft.Restart any terminal windows or otherwise make sure the new PATH is used by your applications. If you have multiple versions of Oracle libraries installed, make sure the new directory occurs first in the path. Add this directory to the PATH environment variable.Unzip the packages into a single directory such as C:\oracle\instantclient_19_3.All installations require the Basic or Basic Light package. Download the appropriate Instant Client packages for your platform.For example, Oracle Call Interface 19, 18 and 12.2 can connect to Oracle Database 11.2 or later. The USB drive will also need to have 8GB or more of capacity.See the Instant Client Home Page for more information about Instant Client packages.Ĭlient-server version interoperability is detailed in Doc ID 207303.1. Before you get started, make sure you don't have any important files on the USB drive, since they'll be deleted during the process. This can take your ISO file and flash it onto your flash drive so you can boot from it. If you want to create a USB installation media you can use for other PCs or for a clean installation, you'll need a program like Rufus. Plus, this method also lets you install Windows 11 on hardware that's not officially supported. You can do that using the ISO you've already downloaded. However, if you want to perform a clean install or format your PC, you may need to create a bootable USB drive. Double-click the ISO file, run the setup file, and you're good to go. As we've mentioned above, if you download an ISO file and you just want to upgrade to Windows 11, you can actually mount the ISO in Windows and run the setup file from there.
