Starting with AutoCAD OEM 2023, the MSI created from the OEM Installer Wizard **must be digitally signed, otherwise the installer will not run** at the end user site.  
After obtaining a digital certificate from a trusted certificate authorities (CAs), you can specify the certificate file and settings to use for signing the MSI file on the Digital Signature tab of the OEM Installer Wizard.  
The whole procedure is explained in [this short video](https://youtu.be/kXoaFCB2ZQw).

Just in case this may help you…  
I just saw a strange behavior with one of our partners who was running Windows 11 and VS 2022.  
Everything was set up correctly, but the **InstallWizard digital signing failed**.  
With VS 2022 you get Windows SDK 10.0.22xxx.0, which is for Windows 11:

> **[Windows SDK - Windows app development](https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/)**
>
> The Windows SDK for Windows 11 contains headers, libraries, and tools you can use when you create apps that run on Windows.

Signing from a Command Prompt worked, but to achieve a successful signing procedure from within the InstallWizard, we needed to use signtool.exe from one of the VS 2019 Windows SDKs, 10.0.18362.0 below:
