An update and a reinstall are different
A new package may update an existing application, but that depends on its identity and compatibility. Removing the installed app first is a separate action that can remove local settings or sign you out. Do not assume that an uninstall is required simply because an unfamiliar download page recommends it.
Confirm where the replacement comes from
Use the verified publisher’s route and read its release instructions. Similar logos and filenames do not establish that two packages belong to the same publisher. This directory has not confirmed release histories for the ten listed games, so it cannot identify a file as the newest compatible update solely from a title.
Prepare account access before changing the installation
Check the account identifier you use and whether its recovery email or phone number is still accessible. Follow the publisher’s backup instructions where available. Do not assume that local settings and server-held account information are the same thing. If you cannot recover the account, ask the operator before deleting the working copy.
When the package is rejected
Keep the exact installation message and your Android version. Ask which package is intended for the existing installation rather than trying unrelated files. The IX9 listing includes an update checklist, and the login guide explains recovery preparation. For transfer and storage errors, use the download walkthrough.
