Quick answer
Download MSI Afterburner
MSIAfterburner466.exe · v4.6.6 · ~53 MB · free, from this site
Step-by-step guide
-
1
Download the 4.6.7 build
Get the installer from our download page. Extract the ZIP (about 53 MB) and run the setup file inside. -
2
Allow the VC++ 2022 runtime
On a fresh PC the installer may fetch a small Microsoft runtime during setup — this is expected, so let it finish. -
3
Keep RivaTuner checked
Leave RTSS ticked during install so the in-game overlay and FPS counter work. -
4
Confirm you are on 4.6.7
Open Afterburner and check the version string in the settings or info area so you know the beta installed correctly.
What is new in 4.6.7
The 4.6.7 line focuses on the Voltage/Frequency Curve Editor used for overclocking and undervolting. It adds thermal curve analysis, curve import and export to a text file, and reference-temperature tracking. It also includes experimental monitoring for newer AMD Ryzen 9000 and Intel Arrow Lake CPUs, and upgrades RivaTuner to 7.3.7 with DirectX 12 overlay support, PresentMon and NVIDIA Reflex latency readouts.
Beta vs the 4.6.6 stable build
Choose 4.6.7 if you want the newest curve tools or own brand-new hardware the stable build does not fully recognise. Choose 4.6.6 stable if you want maximum reliability — beta builds can sometimes carry an expiry date, while stable builds never do. You can switch between them at any time.
Supported systems
4.6.7 runs on Windows 7, 8, 10 and 11, in both 32-bit and 64-bit, and works with Nvidia and AMD graphics cards from any manufacturer. Only Windows XP support was dropped after the move to the VC++ 2022 compiler.
