..doc is not a valid Win32 application

THE ABOVE IS AN ERROR MESSAGE I RECEIVE WHEN I TRY TO OPEN (BY DOUBLE
CLICKING) A WORD 2003 DOCUMENT USING WORD 2007.
I CAN OPEN THE 2003 WORD DOCUMENT FROM WITHIN THE MICROSOFT OFFICE WORD 2007
PROGRAMME BUT THIS IS MUCH MORE CUMBERSOME THAN OPENING THE 2003 WORD
DOCUMENT JUST BY DOUBLE CLICKING ON ITS ICON, WHICH IS WHAT I WANT TO BE ABLE
TO DO.
i TRY TO SET THE FILE ASSOCIATION FOR THE DOCUMENT TO WORD 2007 BUT I CANNOT
AS WHEN I TRY TO DO THIS WORD 2007 IS NOT AVAILABLE AS A PROGRAMME IN THE
FILE ASSOCIATION LIST, EVEN IF I BROWSE AND MANUALLY TRY TO INSERT WORD 2007
INTO THE LIST OF PROGRAMS FOR FILE ASSOCIATION IT WILL NOT APPEAR IN THE LIST
OF PROGRAMMES.
I ALSO TRIED A REPAIR FROM WITHIN THE CONTROL PANEL AND THIS DID NOT WORK.
WHAT IS MOST ANNOYING IS THAT I INSTALLED OFFICE 2007 ONTO ANOTHER PC
RUNNING VISTA PREMIUM AND IT WORKS FINE BUT ON MY PC RUNNING VISTA BASIC,
WORD 2007 REFUSES TO OPEN ANY 2003 DOCUMENTS BY DOUBLE CLICKING ON THEM.
ANY HELP APPRECIATED AS I CANNOT FIND AN ANSWER ANYWHERE.....
THANKS IN ADVANCE
