How to Uninstall Mobile Module?

I tried incorporating the ti.barcode module in my code, and that said that it required scandit, so I downloaded that module from their website. After doing so, however, Titanium started giving me the following error:

I tried uninstalling everything related to Android and Titanium from my machine and reinstalling it, only to be given the same error. I tried creating a new mobile project without editing anything and tried running it, and again got the same error. I think this is all happening because Titanium is trying to install the Scandit module, and I'm trying to figure out how to make it not do that. I have not included the module in my tiapp file. Here is everything that is in the tiapp.xml file (id and name omitted):
