If OP Auto Clicker isn't registering clicks in your game or app, the cause is almost always one of nine specific things — and each has a 30-second fix. Work through this list in order. By #5 you'll have it sorted.
Auto clicker not registering clicks in your game or app? The cause is almost always one of nine specific issues: (1) The game runs as administrator and OP Auto Clicker doesn't — right-click and Run as administrator. Solves about 50% of reports. (2) The game uses kernel-level anti-cheat (Vanguard, Easy Anti-Cheat, BattlEye) which blocks all synthetic input. (3) The game is in exclusive full-screen mode — switch to borderless windowed. (4) Hotkey conflict — OBS, Discord, or Steam may have grabbed F6; rebind to F8 or a Ctrl+Alt combo. (5) Click count limit accidentally set — clear the field or set to 0. (6) Antivirus killed the process — whitelist the .exe. (7) Missing .NET runtime, (8) wrong fixed-position target, or (9) DPI scaling issue.
OP Auto Clicker uses the Windows SendInput API directly, which means it's about as reliable as auto clickers get on Windows. When clicks don't land, it's almost never a bug in the app — it's something blocking the synthetic input from reaching the target. Below: the nine causes, ranked by how often they trip up users in our GitHub Issues.
If your game runs as admin (most launchers, all anti-cheat games), Windows blocks input from non-admin apps. Right-click OP-AutoClicker.exe → Run as administrator. Solves about 50% of "no clicks" reports.
Exclusive full-screen mode (DX11/DX12) gives the game a private input pipeline. Borderless windowed reverts to standard Windows input handling, which OP Auto Clicker can reach. In-game video settings → Display mode → Borderless.
Riot Vanguard (Valorant, League), Easy Anti-Cheat (Apex, Fortnite, Fall Guys), and BattlEye (PUBG, Rust) actively block synthetic input. No auto clicker on the market gets through these without modifying the kernel itself — which would mean violating ToS and getting banned. This is by design.
OBS, Discord push-to-talk, Steam screenshot, NVIDIA ShadowPlay, and many games bind F-keys. If pressing F6 doesn't toggle OP Auto Clicker, click the Hotkey field, press a less-common combination like F8, F12, or Ctrl + Alt + A.
If clicks fire then stop after a fixed number, check the Click count field. Setting it to 10 means 10 clicks total. Clear the field or set it to 0 for unlimited clicks until F6 is pressed again.
Heuristic AV engines occasionally false-positive on auto clickers. If OP-AutoClicker.exe disappears from Task Manager mid-run, your antivirus quarantined it. Add an exception in Windows Defender (Settings → Privacy & Security → Virus & threat protection → Manage settings → Exclusions).
Older Windows installs (Win 7/8 without updates) lack .NET Framework 4.7.2. If OP Auto Clicker won't even open, install the latest .NET runtime from microsoft.com/net/download, restart, and try again.
If you set fixed-position mode and the clicks land on empty desktop instead of the game, the saved coordinate is from a previous window position. Click Pick location again with the game window in its current spot.
If you changed Windows display scaling (125% → 150%) without restarting, the saved fixed-position coordinate now points to the wrong pixel. Restart Windows once after any DPI scaling change, then re-pick your click location.
Before debugging the game, confirm the clicker actually emits clicks.
Open Notepad. In OP Auto Clicker, set click type to Right click, interval 1000 ms (one click per second), cursor mode. Hover over Notepad. Press F6.
You should see the right-click context menu pop up once per second. If yes — OP Auto Clicker works perfectly; the issue is the target game blocking input. If no — the issue is OP Auto Clicker itself (work through fixes 6, 7, and 1 above).
Visit our CPS test page. Set OP Auto Clicker to interval 10 ms, cursor mode, position over the test button. Press F6.
The CPS counter should jump to ~100 CPS instantly. If you see 100 CPS in the test but no clicks in your game, you've isolated the issue to the game's input blocking — check fix #2 (borderless mode) and fix #3 (anti-cheat).
Three most common causes, ranked by frequency: (1) the game runs as administrator and OP Auto Clicker doesn't — right-click the .exe and Run as administrator. (2) The game uses kernel-level anti-cheat (Vanguard, Easy Anti-Cheat, BattlEye) that blocks all synthetic input. (3) The game is in exclusive full-screen mode — switch to borderless windowed.
Usually the Click count limit is set. Check the field in OP Auto Clicker — if it's a number, the clicker stops at that count. Set it to 0 (or leave blank) for unlimited clicks. If the field is blank and clicks still stop, your antivirus may be killing the process — whitelist OP-AutoClicker.exe.
Another app is bound to F6. Common conflicts: OBS Studio, Discord push-to-talk, Steam screenshot key, in-game keybinds. In OP Auto Clicker, click the Hotkey field and rebind to a less-used F-key like F8 or F11, or a Ctrl/Alt combo.
Almost always a missing .NET runtime. OP Auto Clicker needs .NET Framework 4.7.2 or newer — install the latest .NET runtime from microsoft.com/net/download. After installing, restart your PC and re-run OP Auto Clicker.
Yes — OP Auto Clicker works in Chrome, Edge, Firefox, and any other Windows browser. Use cursor-follow mode for clicking around dynamic UI, or fixed-position mode for clicking a stable element like a Cookie Clicker cookie. Some sites use overlay scripts that intercept synthetic clicks — rare, but it happens on banking and CAPTCHA pages by design.
