The IDE loads different DLLs from those it includes in standalones. So 
there is a revsecurity.dll (near/next to) the IDE engine on Windows, and 
also one in the Runtime/Windows... folder. The latter is copied into 
standalones, the former is only used by the IDE.

It suggests that you have previously copied a newer DLL over the one 
near the IDE engine - so it works in the IDE... Then when you copied the 
same DLL into the runtime folder, it then works in standalones too.

The DLLs from newer versions aren't guaranteed to be compatible with 
older versions - in the specific case of revsecurity it depends on 
whether OpenSSL has changed its API in a way which causes an 
incompatibility but it hasn't done this very often (fortunately in this 
case, it would seem!).

Warmest Regards,

Mark.
