New install of 10.11.6. Downloaded an app to install. Oh, gatekeeper, right. No "open anyway" button in the popup. OK, will change that in prefs I guess.
Went to prefs, was set to the middle option. Oh, there's Open Anyway there. Click. Installer tries to launch again, and same error pops up, can't open. Tried a few more times more in confusion that something so trivial could be broken, but it appears so. had to switch to open anything option.
