Visual Studio 2017 Community install error - Couldn't download 'Microsoft.VisualStudio.WCF.DiagnosticPack.Msi.msi'

Question

When trying to install Visual Studio 2017 Community I got the error:
Couldn't download 'Microsoft.VisualStudio.WCF.DiagnosticPack.Msi.msi'
Error 0x80096004 there is a problem verifying the signature of a certificate.

Visual Studio 2017 Community version: 15.9.33

Checking the logs I found it seems that the problem is the hash of the file.

Error: Package 'Microsoft.VisualStudio.WCF.DiagnosticPack.Msi, version = 15.0.27005.2' failed to download from 'https://download.visualstudio.microsoft.com/download/pr/7b52e873-c823-471c-b1e9-ca1224f499fa /74a24f8c005b1d09066b357104945dc94d3a18156c0433352a718aefd1a616d7/Microsoft.VisualStudio.WCF.DiagnosticPack.Msi.msi '.

Please, does anyone know how to fix this?

Hi @Leandro Dos Anjos ,

Welcome to Microsoft Q&A!

From your logs, it seems that you have a corrupted package in your package cache. Please clear your %temp% folder and rename or delete the following folder, then repair/retry your installation.
%programdata%\Microsoft\VisualStudio\Packages\Microsoft.VisualStudio.WCF.DiagnosticPack.Msi, version = 15.0.27005.2

By the way, before the installation, please check for updates and ensure that all recommended Windows Updates are installed and completed. And temporarily turn off any anti-virus software.

If it doesn’t work, I need your help to collect more installation logs. Please download and run this collect.exe tool, go to %temp% folder and find the vslogs.zip file, upload it to https://onedrive.live.com/ and share the link here.

Sincerely,
Anna
