Hi,

After upgrade version 8.00 to 8.20 VSTA macros stopped working. The zenon6.ini file has 
[VSTA]
ON=1
CSHARP=1,
the  general application settings "Enable VSTA" in the zenon startup tool is checked. Macros work propely on the other runtime (zenon ediotor and zenon serwer). There is problem only on webclient. Firewall on webclient is turn off. 

What is the problem ?
