I don't think you can add programs into Iconpackager. You just need to change them via properties   

open Icon packager, in the menu on the left select "Icons and cursors", in the window on the right select "Files". At the bottom right there is a "Add Format" button click it, in the popup select the Programs file extension you wish to add to IP's list of skinned icons (or you can add a new one) and press ok..

Now it will appear at the bottom of the list showing in file's. This will allow IP to natively skin all files with that Programs extension, with the icon you choose ..

I hope this is what you were looking for


Remember tho.. the packages you DL may not have that file type extension in it and wont change it until you specifically tell it what icon to use ..



Heres another way. Open a explorer window in the top menu select "tools" In the drop down menu select folder options, in the folder options configuration window select the "File Types" tab.

In the scrolling window find the programs file extension you wish to associate with a specific icon. Highlight it and select "Advanced" button in the "details for extension" area at bottom. In the window that pops up click the "change icon" button at the top right.

A new window will open click the "browse" button to search your drive for the icon you wish to use. Select it, press ok or apply in each window til they are all closed. Now the os will natively skin all files with that programs extension with the icon you choose ..

this way works with XP, im not sure about vista.

Some Icons refuse or seem to refuse to be skinned easily.( C:\ for example seems to fight taking a new icon some times) I think its due to the system icon is in use at the time of applying the package, and the OS caches the old icon and reapplies it at intervals wiping out the change made by IP.
