Error installing Oracle Developer Tools for Visual Studio 2017

Question

I have a problem when I try to reinstall the ODT 2017: I already had it installed, but when I opened Visual Studio and wanted to check the connection it shows the error "The requested .NET Framework data provider is not found. It may not be installed."

I uninstalled it, and then when I wanted to reinstall it, I was amazed at the error that it was still installed, "Oracle Developer Tools for Visual Studio 2017 is already installed. Please uninstall and try again."

I don't know if I have a folder or file in a hidden folder...

Okay, I am not exactly sure why this worked but I don't want to mess with it since it is working great right now.

I had tried all the methods of manually removing Oracle software and none of that seemed to work. I started exploring the command line options and was trying to force an uninstall even though it wasn't installed. I was hoping it would clear something out.

From command line I tried:

ODTforVS2017_122010.exe /V /uninstall

However, instead of uninstalling anything, it launched into the normal install. Only this time, it worked! Go figure.

Just in case this had something to do with it... Just before this, I accidentally started the install for the VS 2015 version which started normally. Was really excited until I realized it was the wrong version. Maybe this cleared something out? No idea...

I have to move on and finish before the deadline. I hope this helps you.

The accepted answer did not work for me, so I had to investigate further. I was able to solve the problem by manually uninstalling the vsix from Visual Studio (using the Visual Studio 2017 Command Prompt):

vsixinstaller /a /u:"Oracle.VsDevTools.15.0"

Then, I simply ran the installer again and it worked.

就我而言，问题是即使在我之前使用向导卸载之后，扩展 (ODT) 仍然在 VS2017 上，但已被禁用，所以我从 VS 卸载它，然后使用向导再次安装它
