If you try to download a file and it doesn’t work, first try to fix the error with these troubleshooting steps: Make sure your internet connection is working normally. If your internet connection. Unable to download from Real.com Why does the download fail every time I try to download a product from Real.com? If the download for a RealNetworks product fails or gives a 'page cannot be displayed' error, it may be caused by one of the following issues.

So I've created an offline installed of VS 2017 Community on my laptop using this command:

vs_community.exe --layout 'D:DownloadsVS Community 2017' --lang en-US --add Microsoft.VisualStudio.Component.CoreEditor Component.WebSocket Microsoft.VisualStudio.Workload.ManagedDesktop Microsoft.VisualStudio.Workload.NetCrossPlat Microsoft.VisualStudio.Workload.NetCoreTools Microsoft.VisualStudio.Workload.Node Microsoft.VisualStudio.Component.TypeScript.2.0

When I transfer the setup files onto my corporate PC (which is behind a firewall) and run the 'vs_community.exe' setup file, all I get is this error. There's no way to bypass the corporate firewall or to make exceptions. How do I install VS 2017 offline? Am I missing something here?

Edit: I have installed VS 2017 on my laptop keeping the internet connection active. Then when I disconnect the internet on my laptop and try installing again, the installer launches! So perhaps there are some dependencies missing on my corporate PC that are now installed on my laptop?

Edit: The above command installs .NET, .NET core, Xamarin, Node.js, TypeScript and C++ for Mobile. The total downloaded size is 13.2 GB.

It worked!! All I had to do was install the certificates into the root CA! Something I missed noticing in the VS 2017 docs:

How to install from the offline installation folder

1. Install the certificates (They are in the 'certificates' folder, which is in your Layout folder. )

2. Simply right-click each one and choose Install PFX.

3. Specify Local machine (not current user)
4. You can use an empty password
5. Run the installation file. For example, run: c:vs2017offlinevs_enterprise.exe

--- Microsoft Docs

Edit: Remember to install the certs using the Admin account on the PC, or it won't work...

Please try to follow this steps:

1. Right click on exe file.
2. Select 'Properties'.
3. Click on the 'Digital Signatures' tab. Now you can see 'signature list'.
4. Select signature
5. Click on 'Details' button.
6. Click on 'View certificate' button
7. Click on 'Install certificate' and follows installation wizard

All certificates within 'signature list' should be installed. I use Windows 10.

Unable To Download Files On Google Chrome

Was doing this for VS Community 2017 and it would install everything and it does the core installation without any trouble. However, if i select to install the universal or .Net development portions it will install it almost completely, but it will fail on two files. It will say that it cannot download the files from the internet. The files exist in the installation directory and I even went and downloaded the files and placed them into the appropriate directories and it still thinks that it needs to download those two files preventing me from completing the installation process. If I just continue it will install everything else except those two files. I've tried this with a few different layout downloads in different forms (ISO, directory, etc) and same issue (so it isn't a bad download or anything, and I'm sure I did that all correctly). The two files are:

If I plug myself online and do a repair it will go grab those two files without having to grab everything else, but it kind of defeats the purpose. Don't expect a solution, but wanted to mention it because all the other problems are related to installing the certs and I can't find anything online about it failing on just a few files.

In my case it was related to CNG key isolation windows service, it was disabled, the solution mentioned in below link:

I have the same issue after uninstalling SSDT for Visual studio 2017, Can't remove and reinstall or update visual studio 2017.I just restart my machine and it's OK.my be you have also to log in as an administrator ( it depends on your machine configuration and what you can do with you current account)

How i solved mine.

1. I downloaded the setup helper from Microsoft website (i downloaded the enterprise installer, because that's the offline installer version i have )
2. I ran the program, and it wanted to download the complete setup, so i cancelled it
3. I ran my offline installer (vs_Enterprise.exe)
4. Then it fixed the issue.
5. I disconnected the internet, and continued with the offline installation

Minecraft Unable To Download Files

Edited to avoid misunderstand

Running the downloaded Visual Studio layout as administrator worked for me. Maybe the VS_Version.exe try to normally download the files because it can't access to files in the layout (sometimes named backup), like me, in my job we have a lot of restrictions and when I ran the VS_version.exe tried to download and get the message error, but when I ran again the .exe as Administrator the installer started normaly, getting the files from the backup folder
