I used Jacob in my Java application to open word file and save to pdf file. It is working in XP OS with both 32 and 64 bit. But when I deploy it in windows 7, it is not working. In detail, it can't save as pdf file, but it can save as docx file.
Any one has any idea , any clue. Thanks for help. I was stuck.
Do I need to do any configuration ? Any one has any working code ?

My Errors:
com.jacob.com.ComFailException: Invoke of: FileSaveAs
Source: Microsoft Word
Description: Command failed
