As I understand it, the Secondary Installer is responsible for installing all of the extra packages that come with Visual Studio. To answer that, we have to look in the Secondary Installer log ( dd_vs_enterprise_SecondaryInstaller_UX.log, inside the %temp% directory). A reasonable question at this point is why was the installer trying to download them in the first place. The ProblemĪs I mentioned in the question, the installation log states that it failed to download the VSIX packages because of the /noweb switch. Bear in mind that this is a bit hacky and may fail if and when Microsoft decides to update their installer.īut first, we have to understand the source of the problem. Well, a week later I have figured it out and I have a solution. I could, of course, install these packages manually, but I want to understand the reason for this error. I have noticed that these are the only VSIX packages in the installer. Web downloads are not allowed when the /NoWeb switch is used.

The virtual machine is not connected to a network. I am using a clean Windows 8.1 virtual machine for this purpose, so as not to mess up my host system.

I'm attempting to evaluate Visual Studio 2015 Enterprise, but have encountered some trouble during installation.
