The installation package for CONVERGE is in a gzipped tar file named converge_install_*.tar.gz (where * represents the release date) that you need to expand. Place the file in a temporary directory where it can be expanded. Expand the tar file to create a new directory that contains the necessary installation files named converge_install_<version_number>-releasedate, where releasedate is the six digit release date of that installation package. Unzip the file and open the archive using the tar utility
tar –xzvf converge_install_*.tar
