Re: DLL usage (General questions)
Zarthan,
I would say 'no, this is not possible', but I've searched a bit and found explanation how to do it.
You should read this article:

but it's up to you to implement it, I have never personally tried it (but I remember one customer using it for wodCrypt in InstallShield and it worked).
