I have recently upgraded from word 2003 to word 2007. Since doing that all
my
old .doc files will not open when I click on them. I have tried using the
set
default program option but it does not let me save word as the default
program. The only way I can currently open word docs is by having word
2007
open and using the open file option. Any ideas?
