Access 2003 packaging wizard and earlier versions of Access? (1 Viewer)

I have developed a small application in Access 2003 which I wish to distribute to some friends who have Access 2000. I have tried using the packaging wizard for 2003, and put the packaged version on a CD and installed it on their PC's. I can then go into the application on their machines but some of the features don't work (eg. some of the reports and charts). Am I expecting too much from the packaged application or should all references be resolved? Is the only way around this to ensure that they have either a) no version of Access b) Access 2003?
