All my pdf files now open in word

... I have somehow done someting that is opening all my pdf files in word rather than my pdf program ...

I'm assuming that this is new behaviour and that you have Adobe Reader or Acrobat (or some other .PDF reaser/viewer/editor) installed.

It would seem that the default file association for the .PDF filetype has been changed from Adobe to Word. This is fairly easy to reinstate.

Reset Adobe Reader for .PDFs

1. Open Explorer and locate a .PDF file. Right-click it. Choose Open with  >, thenChoose default program from the flyout.

Figure 1.0 - Open With dialog 2. TURN ON Always use the selected program to open this kind of file in the lower left. 3. If your Adobe Reader is in the Recommended Programs list, double-click it. The file will open in Adobe Reader. 4. If your Adobe Reader is not in the Recommended Programs list, click Browse and locate your Adobe Reader application. The default location is:

%PROGRAMFILES%\Adobe\Reader 9.0\Reader\AcroRd32.exe

... or more commonly:

C:\Program Files\Adobe\Reader 9.0\Reader\AcroRd32.exe 5. Once that is selected you will be returned to the Open With dialog with Adobe Reader selected within Other Programs. ClickOK to accept it. The file will open in Adobe Reader.

Your .PDF file association should be back to normal.

Perhaps your PDF program has a check box or similar in its Options or Preferences dialog to make it the default viewer for PDF files.

Otherwise:

• Right-click a PDF file in Windows Explorer.
• Select Open With > Choose Default Program...
• Select your PDF program in the list, or browse for it.
• Tick the check box "Always use this program to open this kind of file".
• Click OK.
