Both client runs are from the same command-line, with just the tag 
replaced. Same path, env, everything. But it does seem like a 32/64 bit 
issue somehow.

The working one is a demand-started .EXE, and the broken one is a .DLL, 
but I don't see it getting far enough to care. Both were installed as 
Admin, as that's the Windows7 way. Script was run non-elevated (both times).

Thanks for your thoughts.
