I recently had my computer serviced for a major

May have to uninstall it first, then reinstall it.

Click START button, lower left corner
then click Control panel
then click on add or remove programs

*see if your product is listed(may be under BRODERBUND or other publisher name)
If it IS listed, uninstall it

Or sometimes the UNINSTALL is included in the CD options:
Insert the cd into the drive
go to my computer
find the cd drive
right-click the drive
select "explore"
Look for an Uninstall program

Hope this helps!
