Martin, can you comment? It looks like the 3.0 installer uses 2 copies of msvcr90.dll, where the 2.6 one doesn't. I would have thought that only one is necessary, but Gregor's experiments seem to demonstrate otherwise.
I haven't figured it out myself; it's a complete mess, and Microsoft is heavily wasting our time.
It seems that you absolutely *must* have the manifest file in each directory that has a DLL which links with the CRT. Whether or not separate copies of the DLL are then also necessary, and whether or not that causes two copies to be loaded into the address space, I don't know. HELP!!!!
I'll see if I can wade through the documentation and offer any help.
To reproduce the problem, you probably have to test on a machine which doesn't have the CRT redistributable installed centrally (neither through VS 2008 installation, nor by running the standalone CRT installer, nor by having installed any other software that provides an SxS copy of the CRT).
That shouldn't be hard - I'll set up a Windows virtual machine with no additional software on it and can use that for testing. If you want me to try anything out, let me know and I can do so in a guaranteed clean environment. Paul.
