VB6 Application not integrating with XP

I wrote a very simple VB6 application that stores data in an MS Access db. A user may select various letters or label options which pass variables to MS Word templates which merge with the Access Db and generate the relative output. The application worked just fine with MS Suite 2000 word. However, with MS XP/2002 these functions do not work. I added the most recent components to the application hoping that would work and still nothing.
My next option is to rewrite the letters and labels to use the db only and eliminate the use of Word.
Thank you in advance for your assistance.
