PDF not opening in IE 10 when linked from robohelp 8

It will be really great if you could help me with my query. I am using Robohelp 8. I have created a topic page and linked a pdf file to it as a bagge file so that when one clicks the topic in the TOC, the pdf file opens. When I generate the output, the pdf is opening in IE 8, 9. However, the pdf is not opening in IE 10. Please suggest a solution.
