Your package targets NETFramework,Version=v4.5.2. That means the assembly folder is lib\net452. You are trying to install the package to a higher framework (greater than 4.5) project. Create a project with framework 4.5.2 or rename the package’s lib folder from net452 to the version which you want to target like net45 or net46.
You can target multiple framework too from a single package.
Edit your csproj file like this:
<TargetFrameworks>netstandard2.0;net45</TargetFrameworks>
