WordPress > HTTP Error 500.21 - Internal Server Error

I am running Windows 10 Pro IIS (V10.0.14933.0) on my PC.

I install via Web platform > Wordpress and the associated PHP, SQL etc..

I Start http://localhost/Wordpress/index.php the next error

HTTP Error 500.21 - Internal Server Error

Handler "PHP55_via_FastCGI" has a bad module "FastCgiModule" in its module list

Most likely causes:

<div class="content-container">

• Managed handler is used; however, ASP.NET is not installed or is not installed completely.
• There is a typographical error in the configuration for the handler module list.
• During application initialization, either the application initialization feature has set skipManagedModules to true, or a rewrite rule is setting a URL that maps to a managed handler and is also setting SKIP_MANAGED_MODULES=1.

</div>

I really don't know how to solve this problem

QST I need help can somebody advice my how to solve this problem..

Thanks Rob73
