Installing third party software for ARender 4

In ARender 4.0, the software required by our document conversion micro Service is automatically searched in the variable PATH of the server.

If you want to support mails in ARender, please install and put in the PATH wkhtmltopdf binaries. If your server does not have an X server (Linux only), please install xvfb and run the following commands:

$> echo -e '#!/bin/bash\nxvfb-run -a --server-args="-screen 0, 1024x768x24" /usr/bin/wkhtmltopdf -q $*' > /usr/bin/
$> chmod a+x /usr/bin/
$> ln -s /usr/bin/ /usr/local/bin/wkhtmltopdf

If you want to support Office files, you can configure Libreoffice and / or Microsoft Office if you are running Windows. You can refer to the following section for Microsoft Office. For Libreoffice, just install Libreoffice and make sure the LibreOffice binaries are in PATH.

If you want to support image files (PNG, JPEG, etc.) please install imagemagick on your system and include its binaries in PATH.

If you want to support video files (MOV, AVI, MPG, etc …) please install ffmpeg on your system and include its binaries in PATH.

Aroms2pdf configuration for Microsoft Office

ARender is able to use Microsoft Office for office’s documents.

We propose this tool to validate if the prerequisites are well installed, please you run it if you have any doubts: AromsCheck


.Net 4.5:

Microsoft Visual C++ redistributable 2010:

Microsoft Visual C++ redistributable 2008:

Office 2013 (2016 preferred). Office 365 compatible if you can activate your server using live internet connection. We recommend as well to keep Office up to date.

Windows server 2012 R2 and up. Always install on your Windows server all existing service packs/major updates in order for the conversion to work in the best manner.

  • Launch the rendition using a local account - Administrator or not - (Services > ARender Rendition Service > Log On) that opens Microsoft Office without any issues nor without pop-ups. Pop-ups will hinder the piloted mode of Microsoft Office and will block the rendering process of the rendition server.
  • In order to configure Excel file conversion, please check that the user launching Excel has also a default printer configured (as an example, the default printer that outputs XPS files) otherwise Excel won’t be able to do its work on pageSetup and won’t convert the documents.
  • Please do not use as default printer the printer that is forwarded, this is a printer that is only here during remote desktop session and will stop working as soon as you leave the server
