Quick answer
MSI Afterburner fully supports Windows 11 (and 10, 8, 7), in both 64-bit and 32-bit. There is no special Windows 11 build — download the same free installer from our download page and follow the steps below.

Step-by-step guide
-
1
Download the installer
Get the file from our download page. Extract the ZIP (about 53 MB) and run the setup file. -
2
Allow the VC++ 2022 runtime
On a fresh Windows 11 machine the installer may download a small Microsoft runtime during setup. Let it — this is expected and keeps the download tiny. -
3
Keep RivaTuner checked
Leave RTSS ticked so the in-game FPS overlay works. You can skip it if you really do not want it. -
4
Approve the Windows prompts
Windows 11 User Account Control will ask for permission — normal for a tool that reads hardware sensors. If SmartScreen warns because you are an early downloader, confirm and continue. -
5
Launch and check the skin
Open Afterburner; it detects your GPU automatically and defaults to the MSI Windows 11 skin. Change skins any time under Settings, User Interface.
The Windows 11 skin & quad-fan control
Recent versions ship with the MSI Windows 11 skin in dark and light editions. On RTX 50-series cards with three or four fans, this skin also unlocks quad-fan control, so you can manage each fan group.
Run it at startup
Turn on Start with Windows and Start minimized under Settings, General so monitoring loads at boot. To make an overclock or fan curve persist, also enable Apply at startup. From here, continue with overclocking or the FPS overlay.
Frequently asked questions
Does MSI Afterburner work on Windows 11 24H2? +
Yes. The current build works on Windows 11 including 24H2. If the overlay stops after a major update, a clean reinstall of Afterburner and RTSS usually fixes it.
Is there a separate Windows 11 version? +
No. The same installer works on Windows 7, 8, 10 and 11.
Why does it download something during install? +
Newer builds fetch a small VC++ 2022 runtime on the fly instead of bundling it. That keeps the main download small.
Is it safe on Windows 11? +
Yes, when you use the genuine installer. Overclocking carries the usual small risk, but monitoring and fan control are low-risk.
