MT5 Would not install

 

Good day, 


It's been 2 days that I've been trying to install MT5 on to my laptop.  I keep on getting "Please specify proxy server setup".  It never did that before in the past.  Usually I install it, login then trade.   I tried turning off my firewall, uninstalling my antivirus, updating windows 10... it keeps on asking me to specify proxy server which is weird.   Please help. How can I fix this?
