RA can play on 95/98/ME only. No NT/2000/XP
To install 98 when you have win2000:
1.建w2k应急盘
附件->工具->backup
2.安装w98
3.用w2k安装盘recovery,安装时选R,R
把系统文件检查去掉
Done!
(Thanks for 过河卒的 research!!!)

============================================
CD version support HUGE map; 2. this version is 正版CD，可以上WestWoodOnline and GameSpy;这样平常想找人打就可以上gamespy or WWL了。可以多练练

如果你只是想周末和大家打，不想上Gamespy，完全可以不必download CD版；周末联网还是用HD版的。

HD版共60M，还要下载Kahn；详细的安装见OLD_Readme!.txt 想下载直接去directory:HD_OLD_YOU_CAN_SKIP
