Update PVZ Fusion and back up your saves

Identify what you have installed

Record your game version, platform and translation project before downloading an update. A newer base game version does not guarantee that every translation has caught up. Read the selected package’s release notes and keep your existing installer if you may need to return to it.

Back up the Windows save folder

Close the game before copying saves. The creator lists the original Windows save location as %USERPROFILE%\AppData\LocalLow\LanPiaoPiao\PlantsVsZombiesRH. Copy the whole folder to a separate backup location and label it with the game version and date.

A community package may use a different location or additional files. Follow its own instructions rather than assuming the original path always applies. Install a new PC build into a separate game folder to avoid mixing its files with the old version.

Check Android update compatibility

Keep the existing app until its saves are backed up. Updates from the same project may install in place, but different package names or signatures can prevent this. Chinese, English and alternative translation apps can also keep separate progress.

Use the maintainer’s save-transfer guide when changing projects. Do not assume that uninstalling and reinstalling will preserve progress, or that a save created in 4.1 can be loaded by 4.0.5.

Verify progress after updating

Launch the new build, open your save and check your unlocked content and usual game modes. Keep the untouched backup until you are satisfied that the update works. If progress is missing, stop before overwriting any old files and consult the project’s support instructions.
