The accurate answer is that it all depends upon the permissions of the
account running the software. Typically for most personal or home
computers, the user has administrative privs, but that is increasingly
not the case on university or company owned computers. On these, they
may not have permission to alter files in the Program Files (Win) or
Applications (OSX) folders.

In some cases, again depending on OS and permissions, you can alter the
folders contents directly. In others you application must launch a
process (another app) with elevated privs, where the OS asks the user
for permissions for the elevated privs, and then that app (if allowed)
can make changes.
