Trial version problam .NET Framwork not found

[Franko]

Note images below. Download Affinity Photos on 17 Apr 2021 (Australia) and when installing the downloader states ".NET Framework will be installed by Affinity".  Yet, when opening AP I get the error message >NET Frame instalization Error.  I have gone to Microsoft forum - multiple trys fail.  My computer is a DELL Precision details in the images.  Version of Win 10 below. I have not had the error before.  Thank you for your assistance.

You can download it here: https://dotnet.microsoft.com/download/dotnet-framework

However, you should rather update Windows first, as the version you are using is outdated and support will be discontinued soon.

Is there a particular reason why you installed Windows 10 version 1909 (i.e. from September 2019) only ten days ago?

Just a simple guy trying my best. I had a Dell Prec not being used thus the reset and windows doing it's thing.  I followed your links and update windows 10 yet again
