It would thus be desirable +to be able to extract the Microsoft Cabinet Files from the InstallShield +Cabinet Files in order to be able to install the applications without access +to Microsoft Windows. + +The format of InstallShield Cabinet Files is not officially documented but +there are two tools available for Microsoft Windows that extracts files +from InstallShield installers, and they are distributed with source code +included. These tools are named "i5comp" and "i6comp" and can be downloaded +from the Internet. + +One major drawback with these tools are that for the actual decompression of +the files stored in the InstallShield Cabinet Files they require the use of +code written by InstallShield that is not available as source code. Luckily, +by examining this code with the 'strings' tool, I discovered that they were +using the open source zlib library (www.gzip.org/zlib) for decompression. + +I could have modified i5comp and i6comp to run on other operating systems +than Microsoft Windows, but I preferred to use them as a reference for this +implementation. The goals of this implementation are: + + * Use a well known open source license (MIT) + * Work on both little-endian and big-endian systems + * Separate the implementation in a tool and a library + * Support InstallShield versions 5 and later + * Be able to list contents of InstallShield Cabinet Files + * Be able to extract files from InstallShield Cabinet Files +EOF |
