MT5 windows 11 access violation error 0xc0000005

[dollarbill100]

MT5 recently does not start - it generates no log entries, and nothing in the "Crashes" folder. Windows 11 task manager shows terminal64.exe for a few seconds, then it disappears. Windows event viewer shows an application error - code 0xc0000005, which means access violation.Strangely, the metatester agents are not impacted, they run just fine, only the terminal.

Seems the latest windows patch bundle may have changed some security settings somewhere...

Is anybody else having MT5 startup problems recently?

Here is the windows event viewer log info:

N.B: Interesting fact that exactly same replica of OS, build, installed apps and updates on a different Hardware works without an issue!?!?! Suspect drivers incompatibility!!!

Googling around does not provide any relevant answers -

Attached the two systems specs for confirmation: System1 - problematic, System2 - fully operational

MetaTrader 5 no longer fully supports Windows 7 or Windows 2008 Server (even if it is R2).

Microsoft's support for Windows 2008 R2 also ended Jan 14, 2020.

Thank you Fernando for pointing this!

It is indeed quite valid point, HOWEVER, question remains, whay would identical OS with just different HW works uninteruptedly and performs LiveUpdates like nothing !?!

Not too worried about it, but just drives me nuts to find the core of the issue as I hate mysteries ;-)

the difference is the hardware. If the hardware didnt matter, then I would still be able to run windows 98SE on system hardware today. Your theory is around the wrong way. It is the hardware that is the problem.

Besides, even if it was just drivers, the chances of you finding compatable drivers is very close to nil.

And even if you did. windows update and windows security would detect you had changed the drivers and within a short amount of time -- revert the drivers to the older ones.

@Michael Charles Schefe:

Thank you Michael!

So it is the hardware that matters more in this case, rather than the OS! Well, then this sums it up! :-)

Hope it would be a good answer for someone who comes across this.

Thank you for the prompt and exhaustive participation guys! :-)
