Interop references needs office installation on the target machine. If office packages aren't installed then you are not able to work with word files. Its neither paid nor free. It just works as the license of the office package.

The word interop dll requires Microsoft Office to be installed. For searching text in word, you can simply use Free Spire.Doc.dll (You can get it on NuGet.org by searching Free Spire.Doc).
using System.Drawing;
using Spire.Doc;
using Spire.Doc.Documents;

namespace findtext
{
    class findtext
    {
        static void Main(string[] args)
        {
            //Load Word document
            Document document = new Document();
document.LoadFromFile(@"E:\Work\Documents\WordDocuments\References.docx");

            //Search and highlight word
            TextSelection[] text = document.FindAllString("forming", false, true);
            foreach (TextSelection seletion in text)
            {
                seletion.GetAsOneRange().CharacterFormat.HighlightColor = Color.Yellow;
            }

            //Save
            document.SaveToFile("FindHighlight.docx", FileFormat.Docx);
        }
    }
}
