Sounds to me like the DLL that implements the crypto is missing, in the 
wrong place, or has unmet dependencies.  You can find out the name (and 
presumably the path) of the dll by looking at release_cryptodll_path.

If it's indeed there, then I'd use the dependency walker (from the 
appropriate Windows ddk) to find whether there are any unmet 
dependencies.  That assumes you haven't done anything obscure with the 
path, as the dependency walker needs to run with the same environment 
variables.
