I am trying to install the Visual Studio Build Tools 2017, specifically version 15.9, on Windows 10. Such operating system is running inside a Virtual Machine launched by virtualbox on Ubuntu 22.04.
As I launch the executable, after asking for admin permissions, a small window pops up with a completion bar and a single text label. When the bar reaches 100% and the label says Preparing: C:\Users\...\vs_startup_bootstrapper.json, the whole Virtual Machine freezes, to the point that virtualbox is not responding anymore.
The only other known instance of this issue I have been able to find was reported on the Microsoft forum and was attributed to an antivirus blocking the installer. This seems not to be the issue in my case, as
I have also tried increasing the RAM space allocated to the VM and leaving it be for a couple of hours, supposing that the installer was taking a long time unpacking the necessary files, but this also is no solution.
Furthermore, the exact same problem arises if I try and launch the newest version (2022) of the generic Visual Studio Installer.
How would I go about diagnosing where the issue is?
Allocating more cores to the virtual machine resolved the issue for me.
On a single core VM the issue occurred, but on a 3-core machine it did not.
