Install the package through nuget. but still it will left one file 'Select.Html.dep' which is required for converting html string to pdf. Download it manually from below link. Extract zip file and copy the Select.Html.dep to your bin directory.

How to fix: Conversion failure. Could not find ‘Select.Html.dep’
