New Domian Server and New Exchange Server with Issue installing Exchange 2019

Question

I created a whole new Domain Server 2019 and have an Exchange Server 2019 and trying to install Exchange with the install Wizard and am stopped at 8 of 14.

Error:
The following error was generated when "$error.Clear(); 
                    $agentName = "Mobile Message Receive Agent";
                    $agent = get-transportagent -Identity:$agentName;
                    if ($agent) {
                    uninstall-transportagent -Identity:$agentName;
                    };

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Thoroughly verify all the prerequisites. E. g. dotnet and vc++ versions. https://docs.microsoft.com/en-us/exchange/plan-and-deploy/prerequisites?view=exchserver-2019 — Vadim, Mar 14 '19 at 06:49
Yeah I think @Vadim is probably right, you're missing a pre-requisite. Also make sure that you aren't trying to install Exchange on a Domain Controller. — duct_tape_coder, Mar 14 '19 at 19:54

According to the error info below, I suspect that the installation package lost the file named 'Microsoft.Exchange.Transport.Extensibility'. Please have a try that redownloading the package and installing again.

"System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Exchange.Transport.Extensibility, Version=15.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified."
