I purchased excel 2007 update last year. i have installed on 5 of my
computers. one of them crashed. i now have a new computer. after i installed
on my new computer and then activated. i get a message that i have installed
my final time. I have one computer that i installed as a backup. can i
uninstall from that computer and reinstall on my new computer that i will be
using all of the time? If i have to purchase a new upgrade again, do i have
to uninstall then reinstall, or can i just change the activation keys, and if
so , where do i go to do that.. Please help...been trying for hours for this
simple problem..
