Im getting the following error in 32 bit machine classic applicationpool

     Handler "PageHandlerFactory-ISAPI-4.0_32bit" has a bad module "IsapiModule" in its module list.

and in 64 bit machine

Handler “PageHandlerFactory-ISAPI-4.0_64bit” has a bad module “IsapiModule” in its module list.

If we install isapi and cgi in webservices then this error is not coming. Is there any possible way to allow my program without installiing those in classic applicationpool. and my next question is, how to recognize the isapi and cgi restrictions are installed. Is there any registry check exists or any other check.

Thanks in advance.

    The above answer helped me but needed some additional steps, here is the full process I had to do.

    Go to Control panel -> Programs and Features -> Turn Windows features on or off. Make sure you have the following selected:

    Turn Windows features on or off

    Next, refresh IIS Manager. You should now see ISAPI and CGI restrictions on the root level of features of IIS, click Allow for both versions of .NET v4.0
