>Hmm.... in .Net 4.0, COM can be accessed by using Dynamic. I wonder if a 32-bit COM dll could be accessed that way, running on 64 bit? I think I'll give it a try in a couple of days, just to see what happens. Unless you already know, which is a distinct possibility. <s>
A 32-bit COM server is registered in 32-bit registry. A 64-bit application doesn't access it.
