In my case  the problem was more severe  turns out asp net was not correctly registered   This response worked fine      simply ran the following command at the command prompt   windir  Microsoft NET Framework64 v4 0 30319 aspnet regiis exe -i       If I had been on a 32 bit system  it would have looked like the following    windir  Microsoft NET Framework v4 0 21006 aspnet regiis exe -i

If you are running Delphi  or other native compiled CGI  this solution will work    As other pointed  go to IIS manager and click on the server name  Then click on the  ISAPI and CGI Restrictions  icon under the IIS header  If you have everything allowed  it will still not work  You need to click on  Edit Feature Settings  in Actions  on the right side   and check  Allow unspecified CGI modules   or  Allow unspecified ISAPI modules  respectively  Click OK

Depending on the type of application  another thing to check is under the Advanced Settings for the Application Pool make sure  Enable 32-Bit Applications  is set to True     I d checked everything in this thread when I had this issue but all had already been setup correctly  I found this was the problem for me

If you look in the ISAPI And CGI Restrictions  and everything is already set to Allowed  then make sure that the ASP NET v4 0 30319 handlers are even in the list  In my case they were not  This can be easy to overlook     I added one for 32  windir  Microsoft NET Framework v4 0 30319 aspnet isapi dll and another for 64 bit  windir  Microsoft NET Framework64 v4 0 30319 aspnet isapi dll  You can name them both the same ASP NET v4 0 30319    Check Allow extension path to execute

In our case the solution to this problem did not involve the  ISAPI and CGI Restrictions  settings  The error started occuring after operations staff had upgraded the server to  NET 4 5 by accident  then downgraded to  NET 4 0 again  This caused some of the IIS websites to forget their respective correct application pools  and it caused some of the application pools to switch from  NET Framework 4 0 to 2 0  Changing these settings back fixed the problem
