Is this a bug? Or I have created the mt5connector.dll incorrectly. I am using VS15

Hi. Can you try install MtApi (MT5) installer from release by link and use MtApi.ex5 from installed pack. Does it has also the crash ?

[KptKuck]

Ok, that works. No crash. I look times if I find the error. Thank you

[danielscotrim]

I got the same error when try to build the mt5connector. The exception happens when the MtApi5 ea calls initExpert. What can I do? Thanks

[danielscotrim]

I figured aout. The MtApiService wasn't updated.

Please contact with me via skype and I will try to help you online, My skype: dem_dw.

Do you still have this problem during call the function?

I am closing this issue because I have not received any answer long time and there are no any new feedbacks about this issue.
