IIS 7 + ASP.NET 4

[ForumBot]

J'ai an ASP.NET application that Je suis trying to convert to an ASP.NET 4 application. The application is fairly simple. J'ai created a nouveau web application in IIS 7.5 pointing to le directory that le ASP.NET application exists in.

When I attempt to execute le application, mais entering [http://localhost:[port]](http://localhost:[port]) into mon browser, I receive le suivant error:

Error Summary

HTTP Error 500.21 - Internal Server Error
Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list



Most likely causes:



- Managed handler is used; cependant, ASP.NET is pas installed ou is pas installed completely.

- Il y a a typographical error in le configuration for le handler module list.

J'ai le même problem quand try publishing SL App using VS2010 bien que there is no prob avant avec .NET 3.5SP1 et VS2008.

So try run this (`%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i`) as described here [forums.iis.net/t/1149449.aspx](http://forums.iis.net/t/1149449.aspx) et here [www.gotknowhow.com/articles/fix-bad-module-managedpipelinehandler-in-iis7](http://www.gotknowhow.com/articles/fix-bad-module-managedpipelinehandler-in-iis7) et It works now. So le problem is ASp>NET 4.0 has pas properly installed, huuu... :)
