How to Install Antidetect Browser — 5 Minute Setup Guide

Installing an antidetect browser takes about five minutes, but a few common snags can stretch that to thirty if you're not expecting them. This walkthrough covers the full path: download → install → activate → first profile → test.

Step 1 — Download the installer

From the product's official download page, grab the .exe (Windows) or .dmg (macOS) installer. The file is usually 75–150 MB because it bundles its own browser engine. Bigger installers usually include more languages and presets.

Verify you're on the official domain. Antidetect browsers are popular targets for phishing copies. Check the SSL certificate matches the company name and avoid third-party download mirrors.

Step 2 — Run the installer

Windows:

• Right-click the .exe → Run as administrator (not always required, but resolves most permission issues)
• If Windows Defender SmartScreen blocks it ("Windows protected your PC"), click More info → Run anyway. SmartScreen blocks anything not yet popular; new releases trip this even when signed
• Choose install location. Default (C:\Program Files or %LOCALAPPDATA%) is fine

macOS:

• Open the .dmg
• Drag the app to Applications
• First launch may show "App downloaded from internet" — click Open (or right-click → Open if Gatekeeper blocks)
• If "App can't be opened because it's from an unidentified developer", go to System Settings → Privacy & Security → Open Anyway

Step 3 — Antivirus exceptions (sometimes needed)

Antidetect browsers include modifications that some antivirus tools flag as "potentially unwanted" — false positive but inconvenient.

If your antivirus quarantines the browser executable:

1. Restore the file from quarantine

2. Add an exception for the install folder (typically %LOCALAPPDATA%\Programs\AntidetectBrowser or similar)

3. Restart the installer if needed

Trusted vendors include the executable in their code signing — fewer false positives but not zero.

Step 4 — First launch and license activation

On first launch you'll see either:

• Sign up flow — create account with email + password
• License activation — paste a license key issued by the provider

Most free tiers use sign-up. Paid tiers use license keys. Either way, the license gets bound to your machine after first activation. Moving to a new PC requires:

• Unbinding from the old machine (via web account page)
• Re-activating on the new one

This protects against key sharing but is annoying if you lose access to the old machine. Document your account credentials and license keys.

Step 5 — Create your first profile

The default UI shows a profile list and a "New Profile" button. Click it.

Required fields:

• Profile name (just for you)
• Browser engine (Chromium or Firefox — start with Chromium)
• OS to emulate (default = your real OS is fine)

Optional but important:

• Proxy — leave as "Direct" or "None" for first test. Add proxies later
• Cookies — start empty
• Fingerprint overrides — leave default. The browser auto-generates a random fingerprint

Click create. The profile appears in the list.

Step 6 — Launch and verify

Click the profile name (or the "Run" button next to it). A Chromium window opens within a few seconds.

In the new window, visit:

• https://pixelscan.net — comprehensive fingerprint test
• https://creepjs.com — secondary verification

Good signs:

• Pixelscan shows all green checks, no "Masking detected"
• Creepjs trust score above 60
• Your IP shown matches your network (or your proxy if you set one)

Bad signs:

• "Masking detected" warning on pixelscan → product is using a weak approach that fingerprint tests catch easily
• Canvas hash identical across profiles → product isn't actually changing fingerprint
• Same WebGL renderer as your real browser → bad fingerprint quality

If you see bad signs, the product isn't worth using. Switch to one that passes pixelscan as a normal browser without warnings.

Common install problems

• "Installer hangs at 99%" — Windows often hangs on first-run cache build. Wait 2 minutes. If still stuck, kill and re-run
• "Browser launches but immediately crashes" — usually corrupted profile directory. Delete %APPDATA%\AntidetectBrowser and re-launch
• "License key invalid" — common cause: copy-paste added trailing spaces. Re-type the key manually
• "Already activated on another device" — your license is bound elsewhere. Visit the web account page to unbind, then retry
