Visual Studio 2017 installer extremely slow

Question

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

This worked pretty fine in the last months and stopped working yesterday.

I already tried to do the following:

• Uninstall VS 2017
• Remove folder %PROGRAMFILESx86%\Microsoft Visual Studio\2017
• Remove folder %PROGRAMDATA%\Microsoft\Visual Studio
• Restart machine

I have a 50 MBit/s download rate and all other apps are working just fine. If I look into the logs I can see failed downloads when I abort the instalation. When I pick one of the URLs there and just download the vsix directly via the browser it just works.

Is there any caching or network setting that might be useful in this case?

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

Has MS issues on certain download servers maybe and what to do or whom to tell in those cases?

Answer 1

change download location via hosts (C:\Windows\System32\drivers\etc) entries:
I checked alternative servers with ping-test.ru

For example:
93.184.215.201 download.visualstudio.microsoft.com
or
68.232.34.200 download.visualstudio.microsoft.com
or
192.229.232.200 download.visualstudio.microsoft.com
or
27.22.54.160 download.visualstudio.microsoft.com

Answer 2

After some heavy investigation and because of the feedback of trinitrotoluol I solved the issue by using an external VPN endpoint. That means, that my German hoster (Telekom) has got problems with some Microsoft download-servers. We contacted them but (not very suprisingly) there is no way to encourage them to examine their network a little bit deeper. So turns out that we have to wait until they fix this back or use a VPN client for such cases.

Answer 3

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