Solution: Associate PDF files with an Adobe Acrobat product.
To check File Associations right Click Start and then click Explore.

Click on Tools and then on Folder Options.

Click the File Type tab and then scroll down to the PDF in the Extensions column. Look in the Details window and make sure you see Opens with: Adobe Reader 6.0 or Acrobat Reader 5.X . If there is another application or no application identified you need to re-associate the file extension.

If Adobe Reader 6.0 or Acrobat Reader 5.X are not listed then you will need to install Adobe Reader from the Downloads and Links page.
