FBM Doctor v1 — Windows first-launch troubleshooter

One-click fix for the most common Windows install errors with FBM Sniper.

Download fbm-doctor.exe from the Assets below, double-click it, hit Yes on the Windows security prompt, and walk through the 5 prompts.

What it fixes

1. Adds the Windows Defender exclusion for %APPDATA%\fbm-sniper-community\ — the #1 cause of "no chrome.exe found" / "corrupted zip" errors.
2. Deletes any partial Chrome download from a previous failed install.
3. Installs the Microsoft Visual C++ 2015–2022 Redistributable if missing.
4. Installs the Microsoft Edge WebView2 Runtime if missing (without this, the FBM window is blank).
5. Surfaces the last 40 lines of startup-error.log so you can paste them to support.

After running it

Launch FBM Sniper. Wait for the Chrome ready status before clicking Start.
