Clean Install & Uninstall (Mac and Windows)

A clean reinstall fixes most desktop software problems — crashes, the app not opening, connection failures after an update. Follow the three steps in order; the restart in the middle matters.

Step 1 — fully uninstall

Use an uninstaller tool so no leftover files interfere with the new installation:

• Mac: AppCleaner (free) — drag the Scanmarker app into it and remove everything it finds.
• Windows: IObit Uninstaller (free version) — uninstall Scanmarker including leftover files.

Step 2 — restart your computer

Don't skip this. Restarting ensures the previous installation is completely cleared before you install fresh.

Step 3 — reinstall

Download the latest version from scanmarker.com/services and install it.

Mac: "malicious software" / malware warning during install?

That message usually means you're installing a software version meant for an older macOS. Download the current Mac installer directly here and run it instead.

Prefer to skip installing altogether?

The full Scanmarker experience also runs in Chrome at app.scanmarker.com — no installation required.

If problems persist after a clean reinstall, submit a request and tell us your operating system version and what happens when you try to open the app.
