 Description

An exception is thrown if the Image Region is not installed. I suggest to check if the image region assembly is loaded and then ask to install the plugin with a popup message.

In SMath 6398 and Maxima SVN 2418 it is possible to insert a draw region even if the ImageRegion plugin is not installed

I think that a simple  PluginsManager.IsPluginInstalled("63ddaef8-9a56-4ff6-938e-d590b638bf99") should be enough (to enable/disable the context menu items or as I've written, to show a popup insted of inserting the region)

Obviously, the Maxima draw regions rely on dlls from the ImageRegion plugin without giving SMath a chance to recognize this dependency.

Would there any problems to be expected, if the libraries were included in the Maxima Plugin and thus might occure twice in the extension folder (with some bad luck in different versions)?

As Kay won't have much time for SMath in the next months, I shall try to mitigate the problem by issuing a new portable distribution with the plugins pre-installed. This, however, has to wait until the recalculation problem upon inserting/deleting blank lines is resolved.
