SDL Trados 2019 - Error 5100 during installation

Question

When installing on Windows 10 64bit-Version I get this error during the installation of the 4.71 .NET framework. 
 There is no "error 5100" in this forum or any other files on the support pages. 
 I loaded down the 4.72 and tried also with the trial version but to no avail. 
 
 All the .NET-framework version won't be installable on this NEW SYSTEM! The pc is only supposed to have work with the SDL Trados GroupShare Software

Hi Thomas Ischler 
 The support team have seen a few cases, possibly asisted by a recent windows update. In the vast majority of these cases the users did not have windows up to date (.NET Framework 4.7.2 is not supported on: &ldquo;Windows 10 1507&rdquo; & &ldquo;Windows 10 1511&rdquo;). Some of them came back saying that after the OS upgrade that the installation was OK, the others did not reply (but they haven&rsquo;t logged any other Cases). 
 In the other cases the installation was performed from the modules, and everything was fine. So you could attempt a manual install by installing the separate modules one by one from these locations: 
 c:\ProgramData\Package Cache\SDL\Dependencies\ 
 c:\ProgramData\Package Cache\SDL\SDLTradosStudio2019\modules\ 
 It could also be that: - There is a problem with the 4.7.2 version installed on your machine and a repair of that .NET instance should be done. - There is a problem with the Windows image on that machine 
 But if all of this seems a bit complicated I would recommend you log a case so a support engineer can look at this for you. For licensing or installation issues that prevent you from working we have a route for all customers to get help. This can be achieved really quickly using this link: 
 gateway.sdl.com/liveagentlicensing 
 You have two options: 
 1. Submit a case using a webform 2. Use live chat to get a licence reset 
 You want to use the first option and make sure that you refer to this thread so the teams can see what you have tried already.

 Just in case you are searching in the wrong place... you do it like this:
