I am attempting to install the Visual Studio 2026 Community Edition on Windows 11 but the bootstrapper consistently hangs at "Downloading: 0B of 0B". No data transfer occurs.
I have performed extensive troubleshooting, ruling out most common causes. The issue persists even after all known fixes are applied. I have attached the vslogs.zip file generated by the Collect.exe tool.
Here is a summary of the troubleshooting I have already completed:
System and Security Checks (All passed or implemented):
Ran installer as Administrator.
Verified that core Windows 11 system files are healthy via DISM /Online /Cleanup-Image /RestoreHealth and sfc /scannow. Both commands completed successfully with no integrity violations detected.
Confirmed that the Windows Defender Firewall and Real-time protection were temporarily disabled during attempts (though Defender kept trying to turn itself back on).
Performed a Clean Boot of Windows to eliminate third-party software conflicts. The issue persisted during the clean boot state.
Network and Connectivity Checks:
Reset the entire network stack using the Windows "Network Reset" feature.
Switched DNS settings to manual Google Public DNS (8.8.8.8, etc.) and configured DNS over HTTPS (DoH) templates for both IPv4 and IPv6 to bypass ISP filtering.
Edited the Windows hosts file to manually force an IP address for download.visualstudio.microsoft.com.
Crucially: I switched entirely to a mobile hotspot network (different ISP and hardware). The exact same "0B of 0B" failure occurred, confirming the issue is specific to my PC's configuration, not my home modem/ISP.
Verified that TLS 1.2 and 1.3 are enabled in Internet Options (inetcpl.cpl).
Installation Attempts:
Cleared the %ProgramData%\Microsoft\VisualStudio\Packages and Installer folders.
Used the command line to attempt an offline installation layout (--layout) which also stalled at 0B.
Current Status:
The issue seems related to a specific internal Windows policy or certificate check that is failing locally on my PC despite all standard fixes. I have generated logs as requested.
I have uploaded the vslogs.zip file to my OneDrive. Here is the link:

The solution that worked for me was to not use the cmd or PowerShell prompt for the installation but to right-click the installer, in my case vs_Professional.exe and run as administrator. I was already logged in as an admin and ran PowerShell as an admin with appropriate switches without success. This process allowed the installation to proceed. However, no packages were selected...this was a clean install of VS2026. Packages were selected and the installation proceeded.

Hello @Luis Alberto Hernandez Muñoz ,
From the logs you provided, it looks like the bootstrapper can't fetch or can't validate the channel manifest rather than a basic network block.
Usually, the easiest way to resolve this is to create an offline layout on a healthy machine and move it to the target machine. The offline layout will contain all the necessary files and certificates needed for installation.
If you have access to another machine with a working internet connection, you can create an offline layout by following these steps:
VisualStudioSetup.exe --layout c:\localVSlayout --lang en-US
On the target machine, make sure to:
Local Machine -> Trusted Root Certification Authorities.Local Machine -> Trusted Root Certification Authorities.--noWeb:
vs_setup.exe --noWeb
If this does not resolve the issue, the last resort would be to perform a clean installation of Windows. Or you can reach out to Microsoft Support for further assistance.

Hi everyone, I also get an issue with offline installation.
I already download the layout and store it on a server.
I have to make the installation of many PC so I don't download the layout on every machines but I set the path of the layout to my remote server like it : \MyRemoteServer\VS26Layout\vs_professional.exe --channelUri "\MyRemoteServer\VS26Layout\channelManifest.json" --noWeb --force --removeOos true --downloadThenInstall --noUpdateInstaller --includeRecommended --includeOptional
But I have many issue .
First, the channel isn't found, the log said that the path isn't correct . I thnik the installer exe isn't able or allowed to go on remote server.
So , to get further , I copy the channel en catalog json on the local machine, but when I start the installation, It still failed cause the installater cannot get the file of the layout from my remote server.
So can you tell me honestly if using a remote server to stock the layout is possible ?
I do it because I don't want to copy the layout ( 70 Go ... ) on every machines ...
Thank you !

It seems you've already performed extensive troubleshooting for the issue with the Visual Studio 2026 Installer hanging at "Downloading: 0B of 0B". Here are some additional steps you might consider:
C:\Program Files (x86)\Microsoft Visual Studio\Installer and then rerun the installation bootstrapper. This action reinstalls the Visual Studio Installer files.These steps should help you further diagnose or resolve the installation issue. If you find specific errors in the logs, those can provide more targeted troubleshooting steps.
