How to add custom extensions manually

Overview

In most situations, the CAST Imaging Express Analyzer automatically downloads and installs the required extensions from CAST Extend . However, where a custom extension is not available on CAST Extend, it is possible to force-install it by placing its .nupkg file directly in the plugins folder before running an analysis.

Before you begin

Note the following rules before placing any files in the plugins folder:

• The folder must contain only .nupkg files - do not place already-unpackaged extension folders here
• All dependencies required by the extension must also be provided as .nupkg files in the same folder, otherwise the analysis may fail
• Place only one version of a given extension in the folder at a time

Step 1 - Obtain the extension in .nupkg format

Obtain the custom extension in .nupkg format. If you receive a .zip or other archive file, unpack it first to locate the .nupkg within.

Step 2 - Place the .nupkg file in the plugins folder

Place the .nupkg file (and any required dependency .nupkg files) in the plugins folder for your environment:

Windows

C:\CAST\Imaging-Express-Online\plugins

Step 3 - Run the analysis

Run the next analysis as normal. The extension will be automatically force-installed at the start of the analysis - no manual restart or additional steps are required.

Removing an extension

To uninstall a custom extension, remove its .nupkg file from the plugins folder. It will be automatically uninstalled at the start of the next analysis run.
