# How do i fix my Error & bug ?

### What to do if Chams++ won't start?

* Remove Faceit anti-cheat and Riot Vanguard using software uninstalling. Anti-cheats prevent cheats from working;
* Turn off all antiviruses on your computer, and turn off Windows Defender (Real-time Protection) completely.<br>
* Make sure you have the correct version of Windows installed. EFT Chams++ only works with Windows 10 (20h1, 20h2, 21h1, 21h2, 22h2) and Windows 11 (21H2, 22h2, 23h2).
* If you see a vulnerable driver failure during startup, then you need to download [this file](https://mega.nz/file/uURS0ZgL#gn9i_rBW__80V9uzexA_Cr2vPUPNGQK2aif4qtevXHs). Run the file and restart your PC, then try to run the cheat again. You also need to disable kernel isolation and Vulnerable Driver Blocking in Windows Defender.
* To run the cheat, you must also disable Reputation-based Protection

Open the start(windows) menu and search for “Reputation-Based Protection.” Open this window.
