Customer says this works just fine, thank you, on (several) windows 7 64-bit machines. It fails on my development system. (How's that for a switch?)
The program(s) are built using 32-bit attributes. (Runs fine, of course, on 32-bit.) It uses 32-bit Oracle (works for me too on 64-bit) and two other 32-bit unmanaged dll's. (N.B. I only have 32-bit Oracle installed, not 64-bit.) These two connect via TCP with a server program, but I cannot see that they are, in fact, connecting to the server, but I AM getting to the dll's.
I'm not including any more detailed information because it has to be a configuration thing. Ether that, or the customer is trying to kid the Indians.
Any guesses?
