I'm experiencig a problem with Zorro S 1.66.4 trying to trade with IB:
Zorro is successfully connecting (it shows price data, green square, server time, etc. ) but is displaying the message "!Real account not supported" and cannot place orders. I am using exactly the same Accounts.csv and AssetsIB.csv file as with earlier versions where everything used to be working fine. Any ideas/suggestions what to check and/or test?

The free version supports IB demo accounts only. Have you installed your Zorro S key?

Yes, as usual I have copied the latest key8e.dta into the Zorro folder.
(by the way: is the password included in the zip to be used anywhere?)
When starting Zorro it says:

Zorro S 1.66.4
(c) oP group Germany 2017
Zorro S Subscription

We got similar reports from 2 other users - there seems to be a bug. Please stay tuned, we're looking into the problem.

When I run Z1 Real account not supported ... have Zorro S IB Gateway
but loading data

It was indeed a bug. A fixed version is now uploaded, please download it again.

Works fine now, thanks for the quick fix.

same real account not supported for z8 which does connect but cannot make trades in real account.
