Yes, I faced a similar issue when I switched to Windows 11. The good news is, there’s a solid workaround. First, make sure you're downloading the MT4 version directly from a reliable source. I used this one: https://ex-protrade.com/exness-mt4 – it's the official Exness MT4 download page and works great.
Here’s what worked for me:
Uninstall any partially installed versions of MT4.
Right-click the installer from the above link and choose Properties. Under Compatibility, check “Run this program in compatibility mode” and select “Windows 8”.
Run the installer as administrator again.
If it still hangs, reboot and install with antivirus temporarily disabled (then re-enable it after setup).
It worked like a charm after that. Exness MT4 runs smoothly, even on Windows 11. Let me know if you need help with the setup itself.
Good luck!
