Using already existing installer

Hey there.

I have this .exe installer that was created before hand. It's an open source program called Ethereal. I had made some slight modifications and gave it a new plug-in. This was all well and good, but I want to be able to use the old installer to be able to put my new plug-in in the rightful directory without manually doing it (Ex: Run the Ethereal installer and expect to see my plug-in in the rightful directory).

Can anyone help me out?

Thanks! 🙂

Ethereal is open-source and the script for its installer is freely available. You can edit the script and rebuild the installer with your plug-in included.

Thank you greatly. 🙂
