I just solved the very same error. Which, after research, has multiple causes.
What I found was: If you have .png files in a folder called "assets", for some strange reason it will not install. Delete that folder (in both the /src and in the /bin-debug or /bin-release folders), copy the those .pngs to another folder first obviously (I called mine /img). Then make sure all your .png file references are correctly "re-pathed" in the code (and I ditched all unused files and all .DS_Store files too for good measure) and it installs. I have not found a really good explanation, but working = good. The certificate issues (another possiblity I found posted on the web) turned out to not be my issue, but you may want to look into that too. It's documented on the Bug List too. Hope this helps. Now...can I get some help on my last post? I'm feeling dumb.
