Installing: the one Windows speed bump
Our code-signing certificate is still being issued, so the very first run trips
Microsoft’s SmartScreen filter: a blue box saying
“Windows protected your PC.” That’s Windows saying it doesn’t
recognize a brand-new publisher yet, not that anything is wrong. Two clicks get you through:
Click More info, then Run anyway. You only see this once.
Run RedAceSquadron_Setup.exe. If your browser asks whether to keep the file, choose Keep.
On the blue SmartScreen box, click More info, then Run anyway.
Follow the installer. It sets up everything (DirectPlay, firewall rules, shortcuts) automatically.
Launch RAS Online from the desktop and fly.
Want certainty instead of trust? Verify the file. Open PowerShell and run
Get-FileHash "$env:USERPROFILE\Downloads\RedAceSquadron_Setup.exe".
The result must match this SHA-256, exactly:
Any graphics card from the last decade (the game is from 2001, your PC will laugh at it)
About 400 MB of disk space
Internet connection for multiplayer only; no account of any kind required
The only official download is from redacesquadron.com, and it is free.
The SHA-256 checksum above is published for every release. If you would like to help fund
what comes next, you can support the revival.
