I am trying to install Visual Studio 2017 Community Edition on a Windows 10 machine which was recently reformatted. There's hardly anything installed but it is up-to-date in terms of Windows Updates. I have no Antivirus software and no firewalls.

When I open vs_community.exe, this process happens about 10 times in a row:

Installer step 1

Then I get this:

Installer 2

I have no options to choose from and no way of doing anything but downloading a 67mb file over and over again.

I've ran the log collection tool and found the following errors:

I can't find a lot on this error. Most of it is Microsoft forums where people are told to "report a problem" but you can't do this for this error because it doesn't get that far into the installation process.

I have tried running the "offline installer" but all this does is launch the same process and fail over and over again. There doesn't seem to be much else that I can try.

I'm really not sure what else to do, does anyone have any ideas?!

  • You have a DNS issue. The error logs confirm that is the case. You should change your DNS provider to something other then you are currently using.

  • I've just tried using OpenDNS, my ISP's DNS and Google's DNS (specified directly in my router). Then tried a hotspot using my phone's 4G and whatever DNS that has. Made no difference.

  • Attempt to download this in your browser. If you cannot then (again) you have a DNS issue. It's possible provider or security software is blocking the download possible. Looks like the installer is ignoring the download due to a certificate error also ("Certificate is invalid"). Discontinue the use of any VPN or Proxy service you might be using.

  • Yeah that downloads fine. i actually downloaded it previously because i was trying to manually specify that file with the installer. Still no luck. No VPNs or proxys in place - direct connection to my ISP and like I said I tried a 4g hotspot too to eliminate the possibility that it's to do with my internet connection.

DNS issue? You clearly can discard that cause he was able to download the installer. If you actually read the log you would figure out and check what it says. Go to certmgr for your account, check in Trusted Root CA certificates and intermediate certificate and see if there is a Microsoft Certificate expired. I found out that my Microsoft Sig PCA was expired. I downloaded a valid one, installed and VS Installer was working perfectly.
