About Expert Advisor Invalid License (538) Error

[Mert Kurt]

Hi there,

I have activated my  Windows 7 Ultimate SP1 operating system with official license of microsoft today.

Right now , I want to use my MT5 ea that i have bought here and installed before..... BUT I am getting Invalid License (538) error in my MT5 terminal right now. IF I REDOWNLOAD MY EA , WILL I LOST ONE LICENSE OF EA? (I DIDNT CHANGE ANY HARDWARE AND ANY FORMAT)

thanks

Unfortunately, since you have changed your Windows License, you will have to re-activate all Market products again.

You can try the Service Desk and explain your issue, but I have my doubts they will do anything about it.

I have read and i understand that , on major OS updates , Metaquotes added 1 license per ea...

I wanted to ask service desk but there is only MQL5 Helper. There is no email or anything. I couldn't contact with anybody with helper. I have got a screenshot that i logged in mql5.com account and and downloaded ea before but there is invalid license error. 

Any admin can help me ? I dont know what can i do

...

... on major OS updates, on hardware changes, on system configurations changes (login to your Windows as admin, and so on) - yes, we may lose activations.

" Metaquotes added 1 license per ea "- yes, that is right. But for everybody. MetaQuotes is not doing to in individual basis (not to me, not to you, not to anyone individually).
It is added for everybody, and we can read the announcement about it from time to time, for example:
Added activations for purchased Market products following Windows 11 Version 22H2 Update release
