Here is a small tutorial on how to add an app to WPI!

Ok this is a sample 10 step (Very simple) configuration for CCleaner (a.k.a. Crap Cleaner).

This assumes you have all of the WPI files in the WPI folder at the root of your CD.

Steps are as follows :

Download the app and place it in the WPI\Install Folder. (CCleaner.exe in this example)
Run WPI.hta and click on the “Config” button\Icon area.
Choose the button at the very top above the config section that says “Add”
Enter in the name section “CCleaner” No quotes! Then click on any other section of the config area to activate the rest of the wizard.
You will notice the Unique ID section gets automatically configured for you.
All apps are selected to be installed by default right from the start so if you don’t want it selected by default you must uncheck this box. Also you can decide if you want this app to be a Forced Install or not.
Choose a category for your app to be displayed in. If you want the app to be displayed in a category you don’t see simply chose other and a box will appear that will allow the entry of you choice.
In the Command 1 section click on the little folder icon and browse to the WPI\Install folder and select the CCleaner.exe installer, this will place the appropriate path in the commandline.
Add the necessary switches for the program to run silently i.e. %wpipath%\Install\CCleaner.exe /s (This can be easily done for most standard apps by simply clicking on the USSF button on the far right of the commandline.)
Select the Save and then the Exit buttons and you have now configured your first app!

Afterwards you configure WPI to run with your CD using whichever method you choose.

Done
