Thanks Kevin, I went back and reread what Finn said after i made the initial post. Just tried it again, put it in /system/app, rebooted, still doesn't appear to be installing. I'm not seeing it in app drawer, add account, all apps in application settings or TB. Changed the settings to match the rest of the files in the system/app folder and still no joy.
When i uninstalled it i was using TB if that helps any.
