It has been reported that sometimes the browsers Edge, Chrome and Safari could block the download of exe file and so of Vega. This depends of the internal setting of your browser or antivirus and not by this site. With the Firefox browser the problem does not exists.

On some Windows machine Vega cannot run and signal the missing of MSVCP140.dll library. To fix the issue please download the missing library from the Microsoft site.
