Converting Word To Pdf using Windows Automation Services

Hi,

I tried to convert word documents to pdf using "Windows automation Services" and followed below links to create event receiver but it is not converting to pdf, then I tried to debug code but I got an error "Unable to automatically step into the server.Unable to determine a stopping location.Verify symbols are loaded.The breakpoint has a filter conditions have not been satisfied".

Any help would be appreciated.

Thank you,
