How Do I create a "Plugin" or " Patch" - I don't even know what to call it.

Hello,

I apologize for being so "Green" with Flexera/InstallShield. I replaced someone here at work, and was actually able
to Load the .Ism file (which is called from a MS Build script - where I excluded files, etc.). I was able to ADD to the installation for
this product. It worked!! I could not believe I could learn this thing on my own. Now I need to do something else.

We have "released" this software I build to customers. They are using it. Some users (not All) need another file a .dll placed in their
c:ProgramData (x86)\Osmose\PPL\Plugins folder. I have been distributing this file to users and having them drop it there. This works,
but I have been asked to "automate" this (without cutting a NEW Release of the product).

It is that simple - the build/installation works great. I can generate a setup (or .msi) file just fine for this product, but now I need to
create this "plugin" (or "Patch") that simple drops a file at a folder location when a user runs it, and that's it.

Can someone tell me how to do this? I would guess this must be pretty easy.

Thanks so much
