In order to work with the JclCompression unit you must have the 7z.dll file in the same path where your exe is located. you can get this file downloding the 7zip installer from here (remember always use 32-bit x86 version of the dll).

for samples about using this unit you can check the project located in this folder

<Path to your JCL library>\jcl\examples\windows\compression\archive

or you can check this question

Hello RRUZ! I did what your answer said. But when i execute the project example the software return: "Cannot load sevenzip library". I just put the 7z.dll in the example folder. Do you have any idea about this problem? Thanks for help! – Delinda

Just debug the sevenzip unit and check why the code fails to load the dll. – Backstage
