I generate an an offline installer for the build tools like this:
vs_BuildTools.exe --layout c:\VS_BuildTools2017_offline --add Microsoft.VisualStudio.Workload.MSBuildTools --add Microsoft.VisualStudio.Workload.VCTools --lang en-US
I move this folder to a build agent (which has no internet connection, and no, it will never have one!), and then execute the vs_BuildTools.exe in that folder even with --noWeb or --noweb, but no matter what option I give, it will always fail with no internet connection available. Surely I am missing something, so any hints on what are appreciated
I also had problems with this.
One important step is to install the certificates before running the installer on the target machine:
- Install the certificates, they are in the "certificates" folder, which is in your Layout folder. Right-click each one to install it. Remember to install the certs using the Admin account on the PC. I.e. not just for the current user.
- Run the installation file.
Answer was originally posted here.
In addition I also noticed that when running the installer on the offline machine it has by default selected some more items than what was downloaded. I had to deselect them to only install the build tools, not the SDK and so on...
But still the install failed, I am currently seeing "An installation file did not download" so I have still not managed to complete the whole install. It's microsoft.visualstudio.vc.msbuild.arm64.vsix maybe it's included in some other component that have to be --added.
Update: Nevermind, my last problem was due to not using --noweb, with it there were no errors.
All steps to install build tools:
- Download build tools
- Download layout files for offline installation:
- Possible workloads are specified here. Following command contains workloads for msbuild and C++ build tools.
- Run (exe file will have some version numbers in name): vs_BuildTools.exe --layout c:\BT2017offline --add Microsoft.VisualStudio.Workload.MSBuildTools --add Microsoft.VisualStudio.Workload.VCTools --add Microsoft.VisualStudio.Workload.WebBuildTools --add Microsoft.VisualStudio.Workload.NetCoreBuildTools --lang en-US
- Copy c:\BT2017offline to box on which you want to install it.
- Open mmc and import all certificates from c:\BT2017offline\certificates to "Trusted Root Certification Authorities" of computer (not current user)
- Run (exe file will have some version numbers in name): c:\BT2017offline\vs_BuildTools.exe --noweb
- Continue clicking next ...
