Visual studio installer crash

Question

I can't install Visual Studio from the vs installer.
The installer starts and then crashes. I've downloaded the log collection tool and I can see this crash in the dd_installer_timestamp log:

[4b18:0001][2021-03-06T18:33:50] Error 0x80131537: Application failed with an uncaught exception: Stringa non riconosciuta come valore DateTime valido.

The error message in english is: "String not recognized as a valid DateTime"

So, some data inside the DeveloperNews feed is preventing me from installing anything! My OS language is Italian

What can I do?

Answer 1

Probably there's an error in the news feed

You can add

127.0.0.1 vsstartpage.blob.core.windows.net

to your host file: C:\Windows\System32\drivers\etc\hosts as a temporary workaround

Answer 2

Hi @shadowings ,

Welcome to Microsoft Q&A!

Please view the similar issue: https://learn.microsoft.com/en-us/answers/questions/297414/visual-studio-community-2019-setup-closes-abruptly.html?childToView=298913#answer-298913

And try to run the following command line from the installer directory (C:\Program Files (x86)\Microsoft Visual Studio\Installer) to launch your Visual Studio Installer:
vs_installer.exe --locale en-US

Sincerely,
Anna
