title: WCF: Handler "svc-ISAPI-4.0_32bit" has a bad module "IsapiModule"
body: <p>When browsing to my .svc endpoint in a browser I get this message: <strong>Handler "svc-ISAPI-4.0_32bit" has a bad module "IsapiModule"</strong> (On 64-bit Windows the message is: <strong>Handler "svc-ISAPI-4.0_64bit" has a bad module "IsapiModule"</strong>).</p>
  
  <p>I can't find IsapiModule anywhere in IIS. How can I fix this?</p>
