I downloaded MT5 but can't reinstall it

There are two solutions: skip this "proxy window" and download stable/official build of MT5 (look at this website about HowTwo: https://www.mql5.com/en/forum/502088)
My solution worked for many people (but for some people - not sorry).

If you are having Windows 10 64-bit computer, and if you downloaded/installed stable/official build of MT5 (it is build 5430 for now) and if  it is still asking proxy during the installation so it may be the following:

  • your computer is not Windows 10 64-bit;
  • you are using Mac computer;
  • you (or your internet/local provider/network) are really having/using proxy;
  • you are using some external VPS which is using proxy (AWS VPS and others);
  • may be more

read the following thread about the suggestions (if it does not help so sorry - you need to change computer or internet provider for example):

seems like you explained totally different issue. what im talking about is that mt5 cannot connect to proxy servers on the pc , it can only connect to remote proxies but when i want to connect to 127.0.0.1 it cannot connect. for some reason it rejects the loopback address, please check it , for so long mt5 has this problem.

I never used proxy sorry ... I hope that experienced users (who is/was using the proxy and how HowTo for example) may help in this situation.

No, I can not reproduce it because I never use any proxy.
I hope the developers will read this thread and they will be able reproduce it (in case this is the bug for everybody and not for you only sorry).
 
Hi please check the Internet settings on windows 10 depends on the Windows you use disable proxy on the settings that may help if the terminal already installed go to options and disable proxy on the terminal to but if you need to install the terminal you will need a stable network thanks.
