One more thing, what version are you using - x86 or x64 (source, or no source)?

Oh, and the .net CLR version, are you using No Managed Code for the application pool?

Here's how to check: https://www.vntweb.co.uk/is-iis-running-64-bit-or-32-bit/

Or, Go to Server Manager > Tools > IIS Manager > hostname > Application Pools > Right click on application_pool_name > Advanced properties;
If the option "Enable 32 bit applications" is set to true, it runs on 32 bit mode;
If the option "Enable 32 bit applications" is set to false, it runs in 64-bit mode.

Is it a fresh install, or an upgrade of 4.30?

If a fresh install, has everything uploaded? Also, have you restarted the app pool?
