Assumption, as they say, is the mother of all fu??ups... In this case, the failed assumption was that a non-standard modification I had been making for many years would continue to work simply because it had in the past. Matt is, of course, quite right. When I changed the "/MT" back to "/MD" in CNF_CFLAGS and rebuilt everything, it all worked like clockwork. My thanks to you Matt - you've solved my problem. Is there a standard (i.e, approved) way of using the static RTLs instead of the DLL ones? Or is my only option to modify the applink code so that it checks its environment in a different way? The problem with the dynamic RTLs is that my application is often used in environments where the user may not have sufficient rights to install the redistributables - whereas, if I use the static versions, the code is a little bigger, but there's no redistributable installation required and I never run into rights issues. Again, thank you for the assistance, Matt - I appreciate it. Cheers! -- David --
