Cannot open Adobe Acrobat email attachments

Operating System: Windows XP SP3
Windows Media Player is default media player.
On saving email attachments that are in Adobe Acrobat Reader format, they show up as _auto_file with the WMP icon and can’t be read unless I go through the process of choosing to open them in Adobe Reader.
A further file type that is defaulting to the WMP icon is PDS for home movie editing. This particular type of file becomes inaccessible and also shows up as _auto_file.
How can I stop the _auto_file function occurring and return the affected files to the correct formats?
Look forward to your advice. Regards Jen

Hi Jen,

In Windows XP you can change the file association simply by saving one of your PDF attachments to a directory or your desktop, then going to that directory or the desktop right-clicking the file and choose Open With in the menu.

Then select Choose Program and select the correct application from the list and tick the box reading Always use the selected program to open this kind of file. Click OK and the problem will be fixed for that particular file.
