Visual Studio Installer silently closes

Question

Hi, today I launched Visual Studio Installer because my Visual Studio 2019 install saied that a new version was available. Visual Studio Installer updated itself and while "preparing" it closed silently. Every time I run it, it closes, so I can't update Visual Studio neither add functionalities. Here is the ErrorInformation.txt: Error Information AppInsightsEvent Name = vs/setupengine/fault Description = Application failed with an uncaught exception: Stringa non riconosciuta come valore DateTime valido.

Hi @Davide Accogli ,

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

Delete the files in the folder C:\Program Files (x86)\Microsoft Visual Studio\Installer. This will not remove visual studio. Then download the visual studio installer and install it again. Once the installer is installed it will give you the option to update visual studio

Answer 3

Thanks you for your suggestion. I did as you said, deleted the files in the folder, download installer and after install it self closes. I took a look at the error and it is the same (invalid DateTime). I assume this is a problem of the new version of the installer, because I have the same error on three completely different PC.

Please, Microsoft, take a look at it.

Thanks
