Question Zeos dbo Problem

Hi , i upgraded to ct 6.7 and now the zeos components error, i.e unsupported database characterset "NONE" found!
Dump your database and recreate it with a "stable" characterset. when inspecting zeos connection component the version is 7.3.0-alpha, how can i revert back to a stable version of zeos components .
I tried both typhon32 and 64, do the same, also tried friebird 2.5 no success.
I use win10, CT 6.7 and firebirb 3.0.
Used to work in previous ct version . i am including a small test app. Please help

Hi, Thank you,
using the zeos 6.62.from lab CT 6.6 worked , did not try zeos old version 7,20-4
Did you manage to test with with new zeos the component verison reports as 7.3.0-alpha

Please refresh my mind how do i revert back to zeos 6.6.1 as the zeos on the latest upgrade 7.0 ct does not open db connection

Thank You, I decided to go for ct lab version 7.10 and zeosdo works properly
