2018.2.8f1 installation problem

So I have this little problem and I seem can’t find the solution.
I tried :

  1. normal run
  2. run as admin
  3. include this exe to firewall
  4. turn off firewall
  5. currently no anti virus running
  6. torrent seems not working

additional info :
I haven’t installed Unity


I could appreciate any help, thank you.

Try to uninstall, clean all files and install again unity fron the original page. (make a secure copy of all your projects before uninstall)
