Automated install of FAB Subtitler

FAB Subtitler can be installed by starting the file setupfabsubtitler.exe with specific parameters.

There may be two scenarios how FAB Subtitler may be installed:

when the USB Dongle is already plugged into the PC and internet connection is available for software activation (INSTALLATION MODE 1)
when the USB Dongle is not plugged into the PC or the internet connection is not available for software activation (INSTALLATION MODE 2)

The procedure is completely the same when installing FAB Subtitler for the first time and also when installing a software update.

INSTALLATION MODE 1 for FAB Subtitler

When the USB Dongle is already plugged into the PC and internet connection is available for software activation the following command line can be used to install FAB Subtitler:

setupfabsubtitler.exe /verysilent /password=password /norestart

During the installation the software activation over internet will be started. If the activation is successful then the correct FAB Subtitler Edition will be installed. If the activation is not successful then FAB Subtitler will not be installed.

You can use the following parameter to write a log file during installation:

/LOG="C:\Temp\FABSubtitler-Setup.log"

The exit code after the installation process is 0 if the installation was successful. If the installation was not successful then the exit code will not be 0 and you should check the log file to see what caused the installation to be aborted.

INSTALLATION MODE 2 for FAB Subtitler

When the USB Dongle is not plugged into the PC or the internet connection is not available for software activation the following command line can be used to install FAB Subtitler:

To install FAB Subtitler STD/PRO/LIVE/MPEG:

setupfabsubtitler.exe /verysilent /password=password /norestart /type=workstation

To install FAB Subtitler BCAST/XCD:

setupfabsubtitler.exe /verysilent /password=password /norestart /type=bcastxcd

Please note that the software license will not be activated during installation and therefore it will be necessary to activate the license during the first start of FAB Subtitler and administrator rights will be required temporarily during activation.

You can use the following parameter to write a log file during installation:

/LOG="C:\Temp\FABSubtitler-Setup.log"

Installation of LAVFilters

To install the latest version of LAVFilters first download the installation .exe file from

https://github.com/Nevcairiel/LAVFilters/releases

and then start it by:

LAVFilters-0.74.1-Installer.exe /VERYSILENT /NORESTART

You can use the following parameter to write a log file during installation:

/LOG="C:\Temp\LAVFilters-Setup.log"

Installation of FFmpeg

To install the correct version of FFmpeg for FAB Subtitler first make sure to download the correct FFmpeg version:

https://www.fab-online.com/publicdownload/ffmpeg-7.1-win32-shared.zip

After that unpack the file to the FAB Subtitler folder into the subfolder ffmpeg.

Powershell script to install FAB Subtitler, LAVFilters and FFMPEG

The following Powershell script (setupfabsubtitler.ps1) can be started by the following command line and make sure that it has administrator rights:

powershell -executionpolicy unrestricted -File C:\path\setupfabsubtitler.ps1

Make sure to enter the correct download path and password into the variables $DownloadUrl and $DownloadPassword. The $DownloadUrl can be in one of the following formats:

https://www.correctserver.com/path/file.zip
or
\\server\sharedfolder\subfolder\file.zip

setupfabsubtitler.ps1:

$DownloadUrl = "https://fabsubtitlerurl"
