这两天安装comsol 3.5a总是提示“Failed to load installation components”，以为是跟之前安装但已卸载的4.0有冲突，清理注册表后，也是这个问题，即使重新下载了其他版本也是这个问题，很是恼人。

根据“see log files for details”，打开log文件进行查看如下：

发现红色标记处的提示，忽然醒悟，是不是金山虚拟光驱的问题，对文件大小有限制导致，因为安装文件超过了4G了，于是，换了UltraISO进行安装，结果很顺利，成功了。呵呵！！小小的收获，以后多注意提示，认真分析问题，这样才能有效快速解决。（UltralSo下载地址：http://data.99pan.com/download/165922_25_2099521851293026852.html）
