Server Manager - Managing Extensions - Error - Missing dependency

When using server manager to install a database, an error regarding a missing dependency like in the following screenshot occurs when selecting the extensions to install:

Below is the step-by-step scenario leading to the problem:

• Try to install a database with some existing extensions

The impact of the problem on the analysis or the dashboard is:

No dashboard created as no installation done

Normally, appropriate dependencies are downloaded when using the extension downloader as documented here: Downloading and installing a CAST extension

Some older initial trial versions of the extensions had incorrect numbering for the extensions and using these instead of the latest functionally released extensions can cause some dependency mismatching.

To fix the problem, proceed as follows:

1. Remove the old extensions from the extension folder. See below for the location depending on the CAST version you are using (in the screenshot above the older extension was for Spring-MVC Web Service 1.2.1)
   1. For CAST 7.3.x, the location is: <CAST_installation_folder>\CustomPlugins>
   2. For CAST 8.x.x, the location is: %PROGRAMDATA%\CAST\CAST\Extensions
2. Download the most recent function release of the extension using extension downloader

More on the versions of the extensions can be seen in the documentation here: CAST AIP Extensions
