I tried to find something online and was not able to find the answer to this questions. But the only thing I can suggest is to call Rosetta Stone directly at 1-800-767-3882 and ask if they offer this Dutch to Spanish learning. Hope this helps. :-)
The language you're going from doesn't really matter, provided you can install the software. All of the language skills are picture based, there is no translation of your language to Spanish. The menu's are the only thing that even tell you want language you're used to speaking and even those aren't necessary to understand as you click on the block to start and then native language doesn't matter.
