No that was my mistake. Actually i want to SharePoint 2007 Add-in in Visual Studio 2015. Not SDK. My apologies.

Hi,
Thanks for your reply, your link which says "We are sorry, the page you requested cannot be found". May i know the issue.

Thank you

Below is the code for converting word files to pdf. In my client location this application is working fine for single user. They are using this app in citrix server. It is working for only single user. But it should work for 15 users at a time.

Error is : Word file is being used by another user.

They are not able to convert the word file to pdf for 15 users at a time.

Please let me know if you need any further information.
