Server.CreateObject Failed in Classic ASP IIS 10

Question

I installed our web application on a new Windows 10 machine, which uses IIS 10.

Our app is 32-bit so I set the app pool to use 32-bit and I also set the web app folder to allow "EVERYONE" full control.

The create object is failing on a DLL we wrote and is in the web app. I have read in other places that the DLL needs to be registered, but I've also been told that only applies to COM+ not .NET DLL's.

The full error message:

Server object error 'ASP 0177 : 800401f3'

Server.CreateObject Failed

/LM/W3SVC/1/ROOT/ERPORTALDASHBOARD/ERPORTALAPP/global.asa, line 443

Solution

You are using classic ASP, so no .NET!. Classic ASP Server.CreateObject uses COM objects.

You may have written an assembly in .NET but to be used from classic ASP you still have to register it:

C:\Windows\SysWOW64\regsvr32.exe pathToYourDLL

BTW: Don't give 'Everyone' full control to the files in your web site.
