Hello Shiva,

I researched the error and found a possible solution for you.

1. Click start
2. Type: cmd
3. Right-click cmd.exe when it appears under Applications
4. Click Run As Administrator
5. Type the following: netsh int tcp set global autotuninglevel=disabled
6. Press enter
7. Restart your computer

Please let us know if that worked for you.
