If you get a message that Oracle Developer Tools (ODT) is already installed, please make sure to:ġ) Close all running instances of Visual Studio.Ģ) Check Add/Remove Programs and try to find "Oracle Developer Tools for Visual Studio" listed there. (For those reading this later on who are using VS 2017, there should be easier ways to uninstall ODT in VS 2017 without using the method above.) Those older versions should overwrite the software you have installed and then when they uninstall you should have a relatively clean environment. If you have trouble with the above, you can try installing and uninstalling ANY version of ODT earlier than 12.2.0.1.1. After uninstalling it, try to reinstall the 12.2 ODT again.

Check to make sure it is no longer listed in Help->About in VS 2015 menus. Then go to the OTN Download page and find that version of Oracle Developer Tools for Visual Studio. Scroll down the list of addins and find Oracle Developer Tools for Visual Studio, and make a note of the exact version. There you should see the version numbers of all the add ins to Visual Studio. Go to Visual Studio 2015 menu -> Help -> About
