Error when running MT5 in windows

[TraderUK67]

When trying to run MT5 on my windows computer (windows 10 Enterprise, Version 1909, Build 18363.1082) i get the attached error message (See screenshot).

It used to work last month but now for some reason it does not (maybe a windows upgrade caused it?)

Error message says: "The procedure entry point SecurityW could not be located in the dynamic link library C:\ProgramFiles\MetaTraderMy 5\terminal64.exe".

I tried uninstalling and reinstalling MT5 with the latest version from my broker and from the MQL5 web site but I get the same error when trying to run it.

MT4 is running with no problem. Problem only with MT5.

Many Thanks for your help!

This is a bad error :)

I recommend reinstalling your windows if it's a very old installation with a lot of upgrades.

I found the following by googling:

This error is mostly caused by a corrupted dll file, other configuration files, drivers, or a bad configuration and can be fixed by either fixing or replacing the dll files, performing a system restore, reinstalling a fresh copy of the application, or updating to the latest version. For a quick work around, try running the 32 bit version of the application if it’s available.

Google 《  The procedure entry point ‘name’ could not be located in the dynamic link library  》

You're going to find tutorials and videos to solve this problem.

Many Thx for your feedback! Much appreciated! Unfortunately this is a recently new windows install and reinstalling windows is something I would like to avoid due to the high effort and time involved... Also all other software on the laptop is running fine.... Maybe other suggestions / options to try first?
