Sqlite vs2017 connections, can't find Sqlite. Interop. DLL?-CodePudding

What I use is: 64 Win10 system, Visual Studio 2017
I find a lot of solutions, the Internet can't and I searched for in the computer, and made a big push SQLite. Interop. DLL
For example:
//C:\Users\Administrator\source\repos\WindowsFormsApp2\packages\Stub.System.Data.SQLite.Core.Net Framework. 1.0.113.0 \ build \ net20 \ x86 \ SQLite Interop. DLL
//D: \ VS2017 \ sqlite \ bin \ sqlite Interop. DLL
.
And I can't add references to add! Tip:
Unable to add on... Reference \ SQLite. Lnterop. DLL, please make sure that the file can be accessed and is a valid assembly or COM component,

Slightly poking fun at once in the access database, system use are quite good, before after changed win10 office before installation is not compatible, a big question, then I want to change to Sqlite, thought just connect once so hard!!!!!!!!!!
