How to install and configure Ghostscript for PDF post-processing

Nutrient Document Converter doesn’t require third-party software for standard operations. However, if you use OCR and PDF/A archiving add-on’s post-processing features, you must install Ghostscript on all servers running Nutrient Document Converter Services.

Recommended Ghostscript versions

We test and recommend specific Ghostscript versions. You can download the supported version using the following links:

• Download 32-bit version (v10.04.0)

• Download 64-bit version (v10.04.0)

Installation options

• During installation, the setup wizard includes an option to download and install the supported Ghostscript version automatically.

• If you’re using an older version of Nutrient Document Converter, or you didn’t select the automatic option, follow the steps below to install Ghostscript manually.

Steps to install and configure

1. Download the appropriate Ghostscript version (32-bit or 64-bit) based on your system architecture.

2. Install Ghostscript on each server running Nutrient Document Converter Services. If you install it in the default location, Nutrient Document Converter will detect it automatically.

3. Configure a custom path if Ghostscript is installed in a non-default location or if multiple versions are installed. Follow the steps below:

• Open Muhimbi.DocumentConverter.Service.exe.config using Notepad. This file is located in the directory where Nutrient Document Converter Services is installed. You can access the folder using the shortcut in the Muhimbi Document Converter Start menu group.

• Locate the Ghostscript.Path key.

• Set the full path to the Ghostscript executable, including the file name — for example, E:\Program Files\gs\gs9.04\bin\gswin64c.exe.

4. Restart the service

• Open the Windows Services Management Console.

• Restart Nutrient Document Converter Services.
