The solution I provide is as follows: First check whether the performance of your graphics card can meet the requirements. The graphics card of Red Alert 3 must have a minimum of 8400. At least 1G of memory. Secondly, check whether the DirectX version is 9.0C. It is not good to have a low or high version. "Start" - "Run", enter "dxdiag" to view. Turn off hardware acceleration, right-click a blank space on the desktop, Properties - Settings - Advanced - Troubleshooting, and turn off hardware acceleration. The third issue is whether you have enough disk space. If there is insufficient space on the C drive before you decompress and install, it will result in incomplete decompression, resulting in incomplete installation, and ultimately the inability to run the game. The last thing is whether you are running a Vista system. If so, you need to turn off UAC before installing the game and then install it. Otherwise, the game is prone to compatibility issues. Control Panel - User Accounts - Turn on or off "User Account Control" and uncheck "Use User Account Control (UAC)". This will make most software compatible with Vista. Remember to re- Start the computer, install Red Alert after restarting, and then turn on UAC according to your own needs. At this point, you should be able to play the game normally. If not, you should try to download the resources again
