10212 - Something went wrong installing a Windows Installer component.WINDOWS安装游戏时候遇到问题
Probably you're installing over old CoH and your Windows Installer database somehow got corrupted.
出现此情况的原因:在原版基础上安装资料片,原版系统安装数据损坏
At least one person has reported that reinstalling their original CoH (without uninstalling first) fixed the problem.
If that doesn't work, here's something to try, no guarantees:
Uninstall Company of Heroes (if you can), then use the Windows Installer Cleanup Utility to remove all entries named "Company of Heroes".
Warning: MAKE SURE YOU KNOW WHAT YOU'RE DOING. The cleanup utility can make a mess of your computer if you use it to uninstall things randomly. ALWAYS TRY TO REMOVE SOFTWARE VIA THE ADD/REMOVE PROGRAMS CONTROL PANEL FIRST! This is a tool of last resort.
