Can't resolve Error Message?

I'm getting the following error message for on my Windows Application (see attached screenshot). It won't even allow me to save my solution or close the solution without this message popping up. I don't get it...

At first, I was getting 4 error messages that were making reference to two unknown files in the "x86\Debug" directory. However, I found these files in saved versions of my solution and placed them there and it still gave me the Error Message.

The file names are "AxInterop.AcroPDFLib.dll" and "Interop.AcroPDFLib.dll".

I can't even save a Form within the Project.
As I said in my earlier post, do you have the dll on your machine, If you don't then that's why you are having problems
Author suggesting its still a problem

The name "SENSITCalibration" is the actual executable file. I looked for the DLL in the "bin" and "obj" directories and it wasn't there. But I don't understand why I can't even perform a "Rebuild". I thought by doing that reinitializes all the settings and it rebuilds the DLL.

So, the point is the DLL was not found. How do I recreate it?
OK, so if that is the exe, then one of its dependencies can't be found. If you right click on the project and select references you can see which files you need.

If you can't rebuild it, what are the errors in the error list, this should tell us what files it can't find.

I did what you suggested and looked at the references...there didn't seem to be anything unusual there (see Screenshot 1). Also, there are NO errors...just a couple of warnings (see Screenshot 2).
What is the error messages after you try to compile? Also are you doing Build all or rebuild all?
BlakeMcKennaAuthor Commented:
That's just it....there are NO error messages...just those warnings. I always do a Rebuild All.
In the output window it will tell you what are the failures if any during a build
