The /UpdCheckDays parameter is only used for new installations. SyncBackSE_Setup.exe /verysilent /language='FR' /SN='XXXXXXXXXX-XXXX-XXXX-XXXX-XXXX-XXXX' /UpdCheckDays='0' /NoBackupPrompt='Y' /Counter='1' For example, to use French, pass a serial number, switch off update checks, not be prompted about a backup folder for old V7 profiles, and not be prompted about visiting the introduction page when the program is run: You can also switch off the prompting about the backup folder when upgrading from V8 to V9 ( /NoBackupPrompt). You can also specify which language the program should use when run ( /language), the serial number to use ( /SN), the number of days between automatic update checks ( /UpdCheckDays - set to 0 to disable update checks, default is 15), and the run counter ( /Counter - set to 1 to not be prompted about visiting introduction web page). If in doubt, you should manually install a test instance first and satisfy yourself there are no contentious issues. You should also bear in mind that if you disable prompting, it is assumed you tacitly agree to those prompts that would normally be displayed (for example, our terms & conditions) and/or that you are aware of the issues that would normally be mentioned. You can also add /CLOSEAPPLICATIONS or /FORCECLOSEAPPLICATIONS parameters to instruct the installer to close applications that are using files that need to be updated by the setup or force close when closing the applications. To prevent the setup from restarting the system, you can add /NORESTART command line parameter.

If it needs to reboot to replace the file then it will immediately reboot, without prompting, once the installation is complete.

Therefore, if the installer cannot replace a file because it is being used, then it will replace it on reboot. WARNING: When using a silent installation, no prompting can be done. It is important that it is the first command line parameter.
