Hmmmm.... so there is a likely problem with 64 bit. I think I'd better load up a machine with WinXP 64 bit and Vista 64 bit to test my application. I sent an inquiry to ChilkatSoft support asking if there were any issues with 64 bit Windows.

>I've tried installing on a couple of machines, and - after consulting the MSDN Knowledgebase (not much) - it appears that the problem is Cryptor is a 32 bit dll and some of the newer servers are 64 bit - and there is a conflict there.
