I initially installed PROIV 7190 on a Linux server and uninstalled by deleting the files on the installed directory and the pro4v7.ini file on the /etc directory. When I tried to re-install, it skipped the part which assigns the port #s and jumps to the end of the installation thus an incorrect install. On PROIV 5 that I previously used, deleting the pro4.ini file allows me to re-install.
