Unzip Utilities
QAD’s Download Center provides product downloads as compressed ISO files in .zip or .7z format. The .7z format is used to overcome a limitation that prevents the zipping of files larger than 2 GB.
To unzip .7z files, use the free 7-Zip utility. Windows, Linux, and UNIX versions of this utility are available from:

Unzipping the compressed product file using the appropriate utility yields an uncompressed ISO file.
