When creating an Asp.net web application, the system prompts that IIS is not running Asp.net version 1.1.

1. If your web server uses a fixed IP address, make sure that "Default web site" is used in your "Internet Information Service" and the IP address in its attribute is "(all are not allocated) instead of the IP address you have specified, and then return to.. net.

2. When the above method cannot solve the problem, consider the solution in msdn as follows:
Visual Studio. NET cannot determine whether ASP. NET 1.1 runs on the Web server computer. This error may occur in several different situations. Check whether the following conditions exist:

A. Make sure that. NET Framework 1.1 is installed on the Web server computer. For more information, see Visual Studio. NET software requirements.

B. If ASP. net has been installed on the Web server computer but still encounters this error, it may be a configuration problem. To correct problematic installation or configuration, you can use the ASP. NET utility named "aspnet_regiis. You can find this command line utility in a path similar to the following: C: \ WINDOWS \ Microsoft. net \ framework \ v1.1.nnnn \, where NNNN indicates four internal version numbers, which can be searched under the maximum version number. Use the/I switch to run this utility: aspnet_regiis/I

Or, from the "Start" menu of windows, point to "program" and "Visual Studio. NET 2003 "," Visual Studio. and then select "Visual Studio.. Net command prompt. After the window is opened, type aspnet_regiis/I.

3. Because IIS does not have the aspnet_filter.dll version v1.1.4322:

We must manually add it to the ISAPI of IIS to open this website for editing with vs. net.

In this way, right-click the website name in the IIS administrator and choose [content] In the attribute ],

Add an ISAPI to the ISAPI tab. In the displayed window, select v1.1.4322 \ aspnet_filter.dll. The priority permission can be ignored.

Or regsvr32 c: \ winnt \ Microsoft. NET \ framework \ v1.1.4322 \ aspnet_isapi.dll
