How to Uninstall and Reinstall PhotoScape X Cleanly

A clean reinstall is the right remedy when PhotoScape X behaves strangely after an update, refuses to open, or carries settings you want to abandon. Because PhotoScape X is a store app on both Windows and Mac, “cleanly” does not mean hunting through folders and deleting leftovers by hand. It means using the operating system’s own uninstall and reset tools, in the right order, so that the fresh copy you install afterwards is genuinely fresh. This guide walks through the process on both platforms, explains the gentler reset option that often makes a full reinstall unnecessary, and covers what to protect before you begin.

Before You Touch Anything: Protect Your Work

Uninstalling an app should not delete the photos you have saved in your own folders, because your exported images live where you saved them, not inside the app. Even so, treat any reinstall as a prompt to check your habits. Confirm that the edited photos you care about are in your Pictures folders or your usual archive, and back them up if they exist nowhere else. If you use PhotoScape X project files or you have customised settings you would hate to rebuild, note them down or export what the app lets you export. Favourites, recent-file lists, and in-app preferences are exactly the kinds of data a reset or reinstall is designed to clear, so assume they will go and keep anything precious outside the app.

On Windows, Try Repair and Reset Before Uninstalling

Windows gives store apps two supported recovery options that are faster than a reinstall. Open Settings, then Apps, then Installed apps, find PhotoScape X, and open its advanced options. Repair is the first step: it attempts to fix the app while keeping its data. If the problem remains, return to the same page and use Reset, which clears the app’s local data and returns it to a first-run state, as if freshly installed, while keeping the installation itself in place. Restart the computer after a reset, open the app, and test the behaviour that troubled you. A large share of “I need to reinstall” cases end here, with the app healthy and no download required.

The Full Windows Uninstall and Reinstall

If Repair and Reset do not help, uninstall completely. From the same Installed apps entry for PhotoScape X, choose Uninstall and confirm. Alternatively, right-click the app in the Start menu and choose Uninstall. When it finishes, restart the computer — this step matters, because it clears temporary files and any lingering state from the old installation before the new one arrives. Then open the Microsoft Store, sign in with the same Microsoft account you used before, search for PhotoScape X by Mooii Tech, and install it from the official listing. Using the same account matters if you own the Pro upgrade, because store purchases and in-app upgrades are tied to the account that bought them; after reinstalling, check the app’s Pro status under that account before assuming anything is lost.

Install only from the Microsoft Store. There is no official standalone installer for Windows, so a reinstall performed from a downloaded file found elsewhere is not a clean reinstall at all — it is a change to an unofficial source, with none of the Store’s integrity checks.

On a Mac, Remove and Reinstall From the App Store

On macOS, quit PhotoScape X first. Then open Launchpad, press and hold the PhotoScape X icon until it jiggles, and click the delete button, which is available for App Store apps; or drag the app from the Applications folder to the Trash and empty the Trash. Restarting the Mac afterwards is a good habit for the same reason as on Windows. Then open the Mac App Store, make sure you are signed in with the Apple Account that originally installed or purchased the app, find PhotoScape X in your account’s purchased list or by searching for the listing by Mooii Tech, and download it again. The current Mac version is 4.3.1, requiring macOS 13 or later, so a reinstall also guarantees you are on the current release rather than an old copy. If you upgraded to Pro, verify its status in the reinstalled app while signed in to the same account.

What a Clean Reinstall Does and Does Not Fix

A clean reinstall fixes problems that live in the app: damaged installations, corrupted local data, and bad settings. It does not fix problems that live elsewhere. If your issue was a file the app could not open, a camera whose RAW files are not yet supported, a HEIC problem caused by missing Windows system extensions, or a photo that was blurry in the original, reinstalling will return you to the same result with a fresher app. Before reinstalling, it is worth one minute of diagnosis: does the problem happen with every photo or one photo, and did it start after an update or has it always been there? The answers tell you whether you are treating the right patient.

What Not to Do

Do not use third-party uninstaller programs or registry cleaners that promise to scrub every trace of the app. For store apps, the system’s own uninstall and reset are the supported mechanisms, and aggressive cleaners can damage the very store infrastructure your reinstall depends on. Do not manually delete system folders associated with the Store. Do not reinstall from an installer file, disk image, or archive obtained from a mirror or file-sharing site on either platform. Each of those shortcuts replaces a tidy, verifiable process with an unverifiable one.

After Reinstalling: A Sensible Setup Pass

Once the fresh copy opens, set it up deliberately rather than all at once. Confirm the app sees your photo folders. Re-apply your preferences gradually, testing as you go, so that if the old problem returns you can tell which setting or step brought it back. Open one familiar photo and run through your normal workflow — a small edit and an export — and check the result before batch work. Then reconnect any optional pieces, such as Pro features under your account. Ten calm minutes here are what turn a reinstall into a genuinely clean start instead of a loop of reinstalling again next month.
