i have finished my project using excel 2003 with VB (micro's)

1- i want to ask if i need to operate my project under excel 2007,,,,can i do that???? is there any code to be in my project to do that

2- i need to make my projects sharing between some users,,,, how can i do that....is that by coding or by using excel option & tools???

3- when iam trying to operate the projects on excel 2007,,, give me some errors,,, it shows that needs some components & references...so, is there any way to collect the componnets & references togather on CD or in my project folder to copy them when needed ????
