I wanted to snoop around the CAB files that Norton AntiVirus uses - but found that they were not Microsoft CAB format (CAB Viewer wouldn't open them).

I saw a installshield decompressor here, but it didn't work.

Is there any way to open those CAB files to add, replace, or remove files?

Sorry for a dumb question, but I just want to see inside the cabs and can't.

a new version of the installshield comp utility has been released.
It should work. You cabn get it from protools.cjb.net
Its version 0.20
Hope that will help.

Morlac

Sorry, the prog. is called I6Comp ver0.20
