翻译下这段英语

给你打出来了：

The installer you are trying to use is corrupted or incomplete.This could be the result of a damged disk,a failed download or a virus.
You may want to contact the author of this installer to obtain a new copy.
It may be possible to skip this check using the/NCRC command line switch (NOT RECOMMENDED)

　　你正在安装的文件被破坏了或者残缺的. 这可能是由于一个damged磁盘,失败的下载或病毒。
　　你可能想联系作者的安装程序获得新的版本。
　　它可以跳过这张支票使用/ NCRC命令行开关(不推荐)。

打得很辛苦啊 望楼主追分。
