Cannot download visual studio in my system

Hi Ashish!

Thanks for reaching out.

Yes, apparently there is a temporary issue on the Microsoft's website. Please try to simply copy the relevant link in a new tab (this worked on my end and I hope it will work on your end, too).
Here's the link for the English version if that's the one you prefer (US):
http://download.microsoft.com/download/0/5/6/056DCDA9-D667-4E27-8001-8A0C6971D6B1/vcredist_x64.exe

Hope this helps.
Best,
Martin
