WebFiguresService does not show result in Matlab.NET deployment

Question

I created a web application and I used webfigureserviceto add MATLAB numbers to my ASP.NET web application. Although, I get a webfigure service symbol on a web page, but it does not display a graph.
Since I did this earlier and in my previous project, adding a link, I found that there was a path GAC_32, but now I forgot how I did it.

Now I'm trying to add webfigureservice.dllto a folder GAC, I can’t access this folder.
Please tell me a simple line-by-line method to follow and get the graph or link to be webfigureservice.dllin the assembly.
