I have a windows 10 X64 bit computer

Hello Brown12345,

Thanks for posting here.

Did you get the error like this?

I think maybe it builds correctly but you're trying to run the .lib like an application. You could right click on the project and select 'Build' like the following show.

After you finish building the .lib project, you will get a .lib file like this.

Then add it to your C++ project. two method:  
    1. Configuration Properties->Linker->Input->Additional Dependencies: add your lib file to the list here.
    2. Use an absolute or relative path, or add directory to
            Project Properties->Configuration Properties->C/C++->General->Additional Include Directories.

Hope this will help you.

Best Wishes,

Jack

What do you mean by "I did this..."?

A library (.lib) cannot be run under the Visual Studio Debugger.  It must be linked into an executable program (.exe).  The executable program can be started under the debugger.

So start a new thread to show us exactly your own situation.
