In a minute, Checker reviews Windows security, anti-cheats, BIOS and drivers and shows exactly what is blocking the launch and how to fix it. It only reads settings: it doesn't disable, delete or change anything.
The things that most often block a launch. Each item tells you where to turn it off.
Finds installed anti-cheats, including those that load with Windows.
What the loader can't start without and what is blocking it right now.

Checker is a small program without a digital signature, so SmartScreen may show the "Windows protected your PC" window. Click "More info" → "Run anyway". The program works offline and sends nothing: the report is saved only on your desktop, and you decide whether to show it to support.
