That was broken a while back. Was it fixed? Also, they inject an old version. At least you could use the old version to install the new one, I guess...
On another note. There is a small glitch with the option to delete a file prior to reinstalling. When the latest FBI says it's already installed, and you press A to delete it and install, it also shows a WRONG_ARGUMENT message, but you press start to continue and then try to install it again, and it installs just fine (so the deletion worked, but there is a glitch between the delete and install... perhaps there needs to be a delay added in before the install?).
