I'm assuming you're on windows. And iyou can browse the web on that machine. If that's the case, you can try disabling Windows Defender Firewall or make a rule to not be blocked by it. windows key > type "control panel" it should pop up before you're finished typing it - hit enter > at the bottom of the control panel should be - Windows Defender Firewall click it > on the left side look for "Turn Windows Defender Firewall Off" (this isn't something you want permanently off) click it > are both boxes checked that say 'Notify Me When Windows Defender Blocks a New App' if not check them and click ok and try to install > if they are checked or install is blocked --- go back to turn off Window Defender and click on both 'Turn Windows Firewall Off" options and hit ok. and try and install again. ---- Afterwards go back to turn off Window Defender Firewall and "Turn Windows Defender Firewall On" with both options and click ok.
