- Install Red Alert 2 with defaults (
C:\Westwood\RA2). - Install the Red Alert 2 1.006 patch.
- Run
Ra2.exeas administrator once. This registers some type libraries as needed. - Apply the required compatibility settings with ra2-compat.reg. This only works if your RA2 path is
C:\Westwood\RA2as advised in step 1, otherwise update this file accordingly. - Download my preconfigured ddwrapper and extract to
C:\Westwood\RA2. (official site) - Edit
C:\Westwood\RA2\ra2.iniso that its[Video]section looks like this (adjust resolution to your display if needed):
[Video]
VideoBackBuffer=no
ScreenWidth=1920
ScreenHeight=1080
StretchMovies=no
After this, Red Alert 2 should be running in glorious HD on Windows 10.

Have fun!
