    Does this answer your question? [Wix and .NET Framework (prerequisites)](https://stackoverflow.com/questions/427775/wix-and-net-framework-prerequisites) – Bob Arnson Feb 26 '23 at 19:27

  • Are you using Wix 4? Why V4 and not V4.8? Key="SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" maybe try 4.72 or Core. See following for different versions : Key="SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" – jdweng Feb 26 '23 at 19:42

You cannot install .NET from another MSI package; only one installation is allowed at a time. https://learn.microsoft.com/en-us/windows/win32/msi/error-codes
