How to "install" sqlite3 on my Windows 10 computer?

So I wanted to get started on Ruby on Rails because it sounds like fun but as I reached part 3.1 over here I ran into some problems.

First I just attempted "sqlite3 --version" in the "ruby cmd" and it came up with: "'sqlite3' is not recognized as an internal or external command, operable program or batch file." So I attempted to just install the sqlite ruby gem and it did that just fine but as I typed "sqlite3 --version", same story. So I just figured you needed to install the thing your self.

So after I downloaded the "Precompiled Binaries for Windows" (64-bit DLL (x64) for SQLite version 3.11.1.) over here I moved the .dll and .def files to my system32 folder, launched CMD as admin and typed regsvr32 sqlite3.dll I get this error message: "The module "C:\WINDOWS\System32\sqlite3.dll" was loaded but the entry-point DIIRegisterServer was not found. Make sure that "C:\WINDOWS\System32\sqlite3.dll" is a valid DLL or OCX file and then try again.

I did a lot of googleing and talked with microsoft support and nothing helped. So im hopeing someone can help me out here. Thanks in advance :)

PS: My PC is "Windows pro 10" 64 bit. If it matters.
