Requesting Help Building Older Scripts

Hello everyone.

I need help trying to diagnose why I cannot build these older scripts. The scripts in question are:
 

-Callouts+ by LukeD1994
-Noose Mod (uploaded by Naruto on GitHub)

I am no "spring chicken". I have a bit of sense of what I'm doing in Visual Studio. My main issues are errors I'm receiving when trying to build the entire project. I will attach pictures so you'll be able to see the errors. I have added proper references (at least visually) but I am still getting errors that make no sense. Examples:

-The type of namespace name [NAMESPACE_NAME] could not be found (are you missing a using directive or assembly reference?)

-The name "ECalloutProbability" does not exist in the current context

-mismatch errors between architectures of ScriptHookDotNet, AdvancedHook, etc

---------------------------------------------------------------------------------------

Other examples you can see in the screenshots. The errors are more or less similar to what I'm experiencing with Callouts+. 

What I have tried:

-Adding references (doesn't seem to help; does take previous warnings that I was missing references)

-Cleaning and Rebuilding Solution
-Changing CPU architecture type for builds

Any help appreciated. It will also help me with trying to build API callout examples as I'm getting the same errors you see above. IDK what I could be missing though...
