Auto install indicators and template to all instance of Meta Trader 4 on a users computer

We have 3 indicators and a custom template that we would like to provide to our clients. But to make things easier we would like an installer program that will run when the install disk is inserted into the computer. After confirming terms and condtions the program will locate all instances of Metatrader 4 on the user's computer and then install the indicators and the template to each of the versions.
