Some people make zips that don`t automatically install into the runtime, they have paths like joesstuff:runtime:libraries So when you install the things they go into a folder called joesstuff instead of the proper place. In your zip program look at the path of the files, if the first drawer name is runtime then they should install correctly. This happens with the pc too, there is no real solution apart from asking the people who make the things to make them install properly.
