Go to the start tab click run type msconfig click ok go to startup and see if you can find Cinepak Cab. If you do then uncheck the box and restart your computer. It also might be part of an already installed program. Hope I helped.
I have no idea what it is or how it got there but everytime I startup my computer, I get a message asking if I want to install Cinepak Cab. I did a search for any files with that name in it but couldn't find any. Do I have to edit a registry or autoexc file? Thanks for any suggestions.
