It has been a few years and I feel a little silly asking where to find the Wire.h Library. I looked in the very long list of libraries in arduino.cc. any help would be appreciated. Now I wil lcontinue my search.

Please don't use code tags for normal text. I've fixed it for you.
The usual location would be somewhere in the Arduino15 directory. It depends on the board package. AVR boards on a Windows system with an up-to-date board package:
C:\Users\yourUsername\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.6\libraries
Note that (part of ? ) the path might be hidden; you can tell Windows to show "system and hidden files"; AppData is usually hidden.
Hello, thank you for the replies. I got past that one and now I am struggling with adding a library to the library folder. (not through the library manager) I have installed Keypad.h to the library folder and I am still getting an error. I am assuming that this is not the way it is done now? I look in the library manager and I do not see any from my Library folder. I did the quick tutorial for the library manager, and it seems easy enough, but I could not Find Keypad.h in the search. Can someone give me a few pointers.
I have an older sketch that I am trying to modify on a new computer that does not have the libraries saved on it. I thought no big deal. I would find them and plop them in the libraries folder. That has been a challenge. Keypad.h is not in the standard library list. So I downloaded it from GitHub and I got this error.
Can any one point me in the right direction? Thank you.
It would always be useful to post the error 
Libraries usually consist of more than one file; just copying the .h file from somewhere is not sufficient.
Installing from library manager using IDE 2.x
Installing from library manager using IDE 1.x
Menu sketch → Include Libraries → Manage Libraries
The Libraries directory is a sub directory of the sketchbook directory; you can find the sketchbook directory in file → preferences; below for IDE 1.x, IDE 2.x will be similar.
And this is the content of the Keypad library on my Windows system
Maybe you could try installing it from the library manager.
If it is available there…….
It is; see post #5
