The most of the archiver programs not supported to create cab files (maybe Winace, try it). But you can download from Microsoft the Microsoft Cabinet Software Development Kit: Microsoft Cabinet Software Development Kit Extract Cabarc.exe file from the archive to the system32 folder on your system. Extract the cab file to a folder and make any changes with Reshacker. Open the command prompt on the folder where your unpacked and modified files have. Then give this command: cabarc.exe n sp4.cab *.* This is one of the all way you can. If you read the cabarc.exe documentation, you will make it more simply.
