Can't open MT5 on my Windows.

Sergey Golubev, 2021.09.09 05:23

1. Windows 32-bit is not supported by Metatrader 5 anymore.
So, Metatrader 5 will not be started/opened in case your Windows is 32-bit.
You may check it when you are able to open MT5:

2. Several traders had this issue (it is what I can read on this forum), and this issue was related to their anti-virus and/or firewall in their Windows.
Yes, several users fixed this issue by themselves, and they told to all of us: "it is issue related to anti-virus and/or firewall."
Two users are from Russian forum and one from this forum.
So, close your antivirus (turn it off) and made an exception in antivirus for Metatrader.

3. beta builds; try to install released/stable version - look at post

4. Are you using some external VPS?
Because some VPS providers were banned from the Market and from mql5 portal.

MT5 error

The MetaTrader platforms will no longer support Windows XP, Windows 2003 and Windows Vista after 01 October 2017.
          Support for Windows XP / Windows 2003 / Windows Vista to be discontinued after 01 October 2017 - General - MQL5 programming forum 2017.06.01

Support for the 32-bit platform version was discontinued 20.03, after the release of build 2361. We strongly recommend upgrading to the 64-bit MetaTrader 4 5 version in order to access all the platform's features without any limitation.

Windows 7 extended support period begins in January 2020 when Windows 7 support ended officially, and it ends in January 2023 for good.

Metatrader 5 not loading on Windows 10

Robert72, 2021.09.12 12:24

Thank you very much Sergey.

Yes, it was indeed my antivirus .

After i add Metatrader folder as antivirus exceptions everything is working .

I switched like 10 days ago from Avira to Avast Free Antivirus.

So for everyone experiencing the same issue :

 Check your antivirus first and make Metatrader folder( located in Program files ) as exceptions .

It worked for me.

BIG thanks to Sergey again.

MT4 Oanda will not launch after install

BohdanPawluk, 2021.09.14 15:24

The problem was with my anti-virus software, I use AVG.

I added an exception to the Oanda Metatrader folder and then everything worked.


 
GR2508 #:

After a long search on the Internet, I found out that the problem is the Antivirus.

So, if anyone here has a similar issue with MT4/MT5 launching (latest versions), try switching off your Antivirus software.

p.s. Sergey, many thanks for all the informational comments anyway.

OMG, Thanks!!! This was the only thing that worked for me installing MT4 on MAC OS!
