Not so much of a question, but more like presenting a straight-up issue I'm having while trying to install Telerik Fiddler Classic v5.0.20211.51073

Every time I try to start the setup, I get this error message (see attachment).

Needless to say I've no idea why my Internet Connection would be the issue, as I'm using it right now to write this. I've already tried running the installer as administrator, compatibility mode, disabling my antivirus and even the firewall to no use. 

Any ideas?

Hello Germán Fredes,

 

The Fiddler Classic installer checks if the required NET Framework version is installed on your machine; if not, it automatically tries downloading it. For some reason, the download from the official link fails on your side, which leads to the error you are seeing. Try downloading and installing NET Framework version 4.5 and above to resolve the issue. After the installation, restart your OS and retry the Fiddler Classic installation.

I thought it was something wrong with my LAN drivers, but it didn't do much. I jumped to NET 4.8 becaused I needed it for another application and the issue is fixed.

You were right, my dude. 

Thanks!
