I am trying to develope 2 C++ apps, one using standard windows libraries and the other using MFCs. The MFC one needs to be an x64 app. The apps require to be run from removable media. Also, nothing is allowed to be installed on the host machines that is not already there.

Because of the x64 requirement I seem to be limited to using VS 2005 as my development environment. But when I use my apps from a memory stick with the CRT library dlls side-by-side I get an R6034 error. - 'An application has made an attempt to load th C runtime library incorrectly'.

Can anyone explain what I'm doing wrong

Thanks Ken. The link you supplied was very useful.

Much appreciated.
