Hi all,

we could finally solve the problem by copying the revsecurity.dll from
LC 9 to the LC 5.x runtime folder! 8-)

I really had no idea that they were compatible!?

Nevertheless I will write to the mothership next week, just to get to
know why everythings works fine in the IDE but not in a runtime.

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.
