Was trying to install SDMove.apk (sideload) from my ICS tablet. adb reported: Failure [INSTALL_FAILED_ALREADY_EXISTS]

However when I issue uninstall command, it reports Failure as well.

When I try to browse all installed apps on phone, i.e. either via launcher, or via the Settings>App menu, the application "SDMove" does not show up.

This is a non-rooted device. How can I fix this issue ?

Could it be the app is already (pre-)installed as a system package? That would be the easiest explanation: A package with that name already exists (so it cannot be installed) -- but being a system packe, you cannot uninstall it. If you know the package name (something like com.foobar.app), try an adb shell "ls /system/app/com.foobar.app" to check if it's there (hopefully this doesn't require root ;) –  Izzy Jan 10 '13 at 7:41
@Izzy, thanks, but I confirm in negative. It is certainly not a system app. Continue to be stumped. –  icarus74 Jan 10 '13 at 7:55
Include me with your confusion -- the above was the only reason I can think of at the moment, sorry. –  Izzy Jan 10 '13 at 10:17
