Scripting Mindvision VISE

Has anyone been successful automating mindvision’s VISE installer? I am specifcally trying to select certain options of a Custom Install. Problem is, some of the sub items of main items have the same name and I can’t script the selection of them. For example, the following checkboxes exist (but Applescript can’t seem to “see” these. Although with VISE you can say Select “Themes” but it will only select the first one, there is no way to get at the second one. Can anyone figure this one out? See an example below:

->English
—> Themes
—> Examples

→ French
—> Themes
—> Examples

I cannot figure out how to select the Themes from the French category
