Answer 1

Hey.

After 45 minutes of this pathetic "unknown error", I was about to give up. Then I remembered that I had a similar issue on another PC while trying to install 4.8 on Windows 7. That issue got solved. So I thought, what if 4.8 is compatible with 4.5? 4.8 installed without any issues and it worked for my needs.

Solution: Install .NET 4.8 instead ( https://dotnet.microsoft.com/download/dotnet-framework/net48 ).

Good luck.

Answer 2

Hi @SWETAK AMITAV ,

Welcome to Microsoft Q&A forum.

Looks like this issue is related to signature verification. Are you using a proxy, some anti-virus software or under a policy group? If you are using some of them, please try to disable them temporarily and retry .net framework 4.5 install.

In addition, I see that you are using Win7 SP1, but did you install all the required(latest) updates, for example, security update for Windows 7? You can refer to this document: Windows 7 SP1 and Windows Server 2008 R2 SP1 update history and match the installed KB packages to see if you have installed the latest update of your Windows 7, and search then download from here: Microsoft Update Catalog if some of them have not been installed.

Best Regards,
Tianyu
