XP Home not giving access to programs

I am running XP home edition. I have installed 2 programs this week and neither will allow anyone but the administrator to access and use these programs. These are not the first programs I installed but these are the first that I have run into this problem with. They also do not show up on the users Start Menus so you have to look in Program Files and double click the exe. How do I fix this so all users have access to these programs?
