Where's the system configuration file the install wizard is asking for?
If you are referencing to the Windows agent install wizard, then the installer is looking for the configuration file that needs to be downloaded from the RSA AM Security console
Refer - Article Generate the Authentication Manager Configuration File
You can then unzip the file downloaded which has the sdconf.rec file
Move it to the machine to where you are running the installer from and point to the sdconf.rec file for the installation to proceed.
Hope the above helps.
If this is any agent install, the configuration file would be what AM people call the sdconf.rec file, which the article Sriranga references explains how to download from AM 8.x Security Console
