Best Cab Builder
I agree with Amalkotey,
The best CAB and Windows Installer program is PPCIC by Aperitto Software. I have tried three commercial trial programs that do this job and PPCIC is simply the best and easiest to use.
It allows you to build a CAB or windows installer (or both), change registry, create shortcuts and a whole lot more.
It is not freeware but if you need anything that is comprehensive, say for freeware or shareware use, then this is the software to trial.
