Path where JS files stored in Siebel IP 17

After installing Siebel IP 17 client in laptop. Below are some of the JS files that are missing from path.

Ex: C:\Siebel\Client\public\SCRIPTS\siebel

1. Applet.js
2. Applicationcontext.js
3. Htmltmplmgr.js
4. Toolbarrenderer.js

   5.   phyrenderer.js

On the UI, everything is rendered properly. In Siebel IP 14, these files were existing.  Some custom code was added in some of the above files and need to incorporate these changes in IP 17.

Let me know the path for these files in Siebel IP 17.

Thanks
