Custom Install Properties

This view allows you to specify one or more additional installer files (.exe or .msi) that are installed with your desktop application. For instance, this is beneficial for applications that include a third-party redistributable component.

In order to use CustomInstall declarations in MSIX, Developer Mode must be enabled before installing the MSIX package and may be disabled after installation.

One method to enable Developer mode is to run PowerShell with elevated privileges and use this command line:

PS C:\WINDOWS\system32> reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock" /t REG_DWORD /f /v "AllowDevelopmentWithoutDevLicense" /d "1"

More methods and other information can be found in this article from Microsoft : Developer Mode features and debugging.
