I used XP for many years. In order to not loose the use of some very important programs when I upgraded to windows 7 I partitioned my hard drive and kept XP on dirve F and installed 7 on Drive C. In the process I was forced to uninstall the most important program I use. Now I want to reinstall it to run on XP (Won't run on 7) but I keep getting the following message.... "Setup has detected that Microsoft DAO is in use. Programs using DAO must be exited before Setup can continue." But NO programs are open for me to close!! Is there a way to get around this? Will greatly appreciate any suggestions.
