Visual Studio 2017 installer is very slow

I tried to install the latest VS 2017 update yesterday and since then I cannot get it to finish this.

This has worked pretty well in recent months and stopped working yesterday.

I've already tried the following:

  • Remove VS 2017
  • Delete folder %PROGRAMFILESx86%\Microsoft Visual Studio\2017

  • Delete folder %PROGRAMDATA%\Microsoft\Visual Studio

  • Reboot machine

I have a download speed of 50 Mbps and all other apps are working fine. If I look in the logs, I see failed downloads when the installation fails. When I select one of the urls and just download vsix directly through the browser, it just works.

Are there any caching or networking settings that might be helpful in this case?

UPDATE I tried 2 downloads (WLAN) from MS servers right now:

Poor download rate from visualstudio.com

Good download rate from MS Download

Are there problems with MS on certain download servers, maybe and what to do or who to say in these cases?

I had the same problem with VS2017 Preview. I disabled IPV6 in the properties of the network adapter. After that, the installer ran at full download speed.

After careful research and feedback on TNT, I resolved the issue with an external VPN endpoint. This means that my German hoster (Telekom) is having problems with some Microsoft download servers. We contacted them, but (not too surprisingly) there is no way to encourage them to explore their network a little deeper. It turns out that we need to wait until they fix it, or use a VPN client for such cases.

Fixed this for me by installing 3 main features first after completion (three above the Visual Studio installer) after it finished, then install another feature.
