windows cannot install required files......
我下载的是“vista_5744.16384.061003-1945_x86fre_client-lrmcfre_en_cn_dvd”版本。在windows xp下用虚拟光驱安装，在安装的过程中展开文件到27％时，出现电脑重启现象。重启后展开文件到30％时，发生错误“windows cannot install required files。The file may be corrupt or missing. Make sure all files required for insfallation are available, and restart the insallation . Error code:0x80070570”无法再安装了。请高手指点！ 谢谢！
