Installing Unity3d fails on Visual Studio.

[alpha0mega96]

exec: msiexec.exe /i "Z:\opt\VRC\install\Download\vstu.msi" /qr 
Error: Error while installing VSTU. (Error code: 1603)

The installer tries to install Microsoft Visual Studio 2015 Tools for Unity. It gives this message from the vstu.msi:

Microsoft Visual Studio 2015 Tools for Unity Setup Wizard ended prematurely because of an error. Your system has not been modified. To install this program at a later time, run Setup Wizard again. Click the Finish button to exit the Setup Wizard.

Please fix?

Sorry, I don’t use Unity anymore, this repo is unmaintained (edit: by me, there might be others) and the Linux Editor is available now anyway.
