Hi mofo,

This is important because there are certain files that are shared by more than one program, such as .dll files. Sometimes when you install a program it will need to install a newer version of a shared file, and if you have a program running in the background that happens to use that file then it will cause a conflict and give you and error that "this file is in use" or something along those lines. Hope that helps.
