Re-downloading app always failing

Question

So, I uninstalled an app, but whenever I try to install that app again on Google Playstore it always ends with an "App not installed" error. The error happens only when the app finishes downloading to 100%. The app that I was trying to install was "World Conqueror 3". So far, I've deleted the cache of Google playstore and even tried uninstalling its updates then tried to download the app again, but it went to no avail. As far as I know, I've completely uninstalled the app before trying to install it again. Is there any fix for this?

Answer

Some apps leave remainders during uninstalls that aid in the restoration of state or level information upon re-installing a later version. Usually these remains are unimportant to a user who does not intend to re-install or to any other user where consistent state or level data is unimportant. These remains have a particular name in an app that can clean them up: "corpse files".



SDMaid is a disk cleaner that can locate, and delete, files related to corpses.
Install the app, and select CorpseFinder from the menu to locate, and, optionally delete them.
