>> 1) On the general tab, the Unique Encryption Code section is not visible.
In a multi-dll app this setting appears in the data Dll. You'll actually find the setting on the Advanced tab of the Secwin settings as well (in 6.22 and earlier.)
From build 6.23 of Secwin the setting will be visible on the General tab, although you'd still have to set it in the data dll.
(So in the short term - add it to the data dll, and set it on the advanced tab there. In the long term it'll be in the data dll, but on the General tab.)
cheers
