本文介绍了解决在IIS服务器上安装.NET Framework 2.0时遇到的兼容性错误的方法。通过使用Microsoft提供的清理工具彻底卸载旧版本及残留文件后,可成功完成安装。

的服务器配置iis上的.net2.0,故障症状为.net framework2.0无法安装提示错误为:
setup cannot continue because this version of the .net framework is incompatible with a previously installed one http://support.microsoft.com/support/kb/articles/q312/5/00.asp

其实是因为之前他安装过.net framework2.0但是没有卸载干净导致的,通过使用微软提供的“.NET Framework Setup Cleanup Utility”将.net framwork2.0和所有残存文件统统卸载,再重新安装问题即可解决。
