When we deploy our conversion code to production server, using Windows Server 2008 - our code gives following error:

Line of code that fails:
HtmlToPdfResult result = html.Convert("http://google.com", ImageType.Metafile, (int)width, -1, AspectRatio.KeepWidth);

MESSAGE: Exception of type 'System.Web.HttpUnhandledException' was thrown.

I have managed to fix the problem by copying microsoft.mshtml.dll into bin folder of my ASP.Net application.

Also, there is another solution discussed here:

Actually, problem is still around.
From time to time application throws error
MESSAGE: Exception of type 'System.Web.HttpUnhandledException' was thrown.

And conversion is very slow even for simple documents...
