正如IE团队多次指出的那样，IETester之类的工具本质上不如使用实际的浏览器进行测试可靠，因为它们使用的方法是不受支持的黑客，并导致崩溃和真实" IE二进制文件与您要测试的较旧版本的二进制文件混为一谈的情况.您应该使用Microsoft提供的免费VPC测试IE6.

As noted by the IE team many times, tools like IETester are inherently less reliable than testing with the real browsers, because the approach they use is an unsupported hack, and leads to crashes and cases where the "real" IE binaries get munged with the older ones you're trying to test. You should test IE6 using the free VPC that Microsoft provides.
