无法使用 Windows 7 SP1 在 IIS 7.5 中添加 ASP.NET 组件

Question

I have tried to add ASP.NET Component in IIS 7.5 From the Control Panel, click Programs and then click Turn Windows features on or off which is listed under Programs and Features, Checked IIS options. While it is saving getting following error :

An error has occurred. Not all of the features were successfully changed

Answer 1

As far as I know, this issue may occurs because a duplicate Internet Server API (ISAPI) filter is detected when you try to install the ASP.NET feature.

I suggest you could try below steps to reinstall the asp.net:

1.Open IIS management console

2.Expand the local computer node, double-click ISAPI Filters, and then remove all the ASP.NET filters that are listed.

3.Re-install the asp.net in the control panel
