Did you point in your Zorro accounts csv to the two different dlls?

"But now I get an error message when I load the ZorroMT42.dll on the chart of MT4." -->> What do you mean here? You would use the EA, not the dll in MT4.


The EA has the ZorroMT4.dll as a dependency, but as far I understand, you need to rename that dll in your Zorro plugin folder.
Then point within the accounts.csv to the repsective dlls.

Now I am not 100% sure, but either you need to copy both then to your MT4 folders and compile the EA and maybe then point to the "missing dll" or something similar.

Best guess, make sure your accounts.csv is set up properly with two differnet dll names.

Then clean up your MT4 install, and do it again.
