Could not load file or assembly 'Oracle.DataAccess, Version=2.112.4.0

I received code from my client, the web.config has following entry:

<add assembly="Oracle.DataAccess, Version=2.112.4.0, Culture=neutral, PublicKeyToken=89B483F429C47342" />

From the compile time error in Visual Studio 2019 in my vb.net project targeting framework 4.0, it seems I have to install Oracle Data Access component.

Error message: Could not load file or assembly 'Oracle.DataAccess, Version=2.112.4.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)  

However from the Oracle site https://www.oracle.com/database/technologies/odac-nuget-downloads.html I am not able to find suitable XCopy file which can fix this error.

I tried 64bit but that does not worked. Further, it is very hard to find which DLL will have the version required in web.config.

Any help please?
