As you can see in the above first image saying: To run this application you must install one of the following version of the .NET Framework. It is just because of required Microsoft .NET Framework version is not installed yet in the Windows 7 machine. So you have to install it at any cost to run the application successfully.

And in the second image while trying to install required Microsoft .NET version is telling: Installation did not succeed .NET Framework has not been installed because: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. It is just because of; now a days you may be aware that Microsoft is not supporting Windows 7 machine as this operating system has End-Of-Life (EOL). Which means Microsoft is not releasing any update after 14 January 2020 for Windows 7 PC. Hence such things happen due to out-of-date operating system configuration. Now here you have to take some manual step in downloading and importing the Microsoft Root Certificate Authority 2011 certificate to successfully install the Microsoft .NET Framework on Windows 7 machine.
