Answer 1

Go to IIS > Site > Authentication, click on "ASP.NET Impersonation" and DISABLE it

Answer 2

I found the problem here-

https://github.com/wkhtmltopdf/wkhtmltopdf/issues/2782

We started by removing all assets (css and javascript) from the document - leaving just images and the html layout. It generated correctly through IIS. We then slowly added back resources, starting with CSS. The moment we added one of our Javascript files back it threw the OLE error again. We removed that and added some simple Javascript to the document (literally var x = 1;) and it still failed.

For some reson wkhtmltopdf cannot find js files...

so i found the solution here-

https://github.com/wkhtmltopdf/wkhtmltopdf/issues/1634

I simply had to change:
<script src="//cdnjs.cloudflare.com/ajax/libs/numeral.js/1.4.5/numeral.min.js"></script>
to:
<script src="http://cdnjs.cloudflare.com/ajax/libs/numeral.js/1.4.5/numeral.min.js"></script>
(added the HTTP).

I also switch on server from ActionAsPdf to UrlAsPdf

And set the url to localhost

string pthx = "http://localhost/Home/exmple?num=" + numtofind;
UrlAsPdf urlss = new UrlAsPdf(pthx) {
    FileName = "REPORT.pdf",
    CustomSwitches = "--print-media-type "
};

I think the wkhtmltopdf can't find host...

Hope it will help you too...
