I am trying to install ATL/MFC 7.1 using the IS merge modules. I believe it should be installed in the WINSYS folder. However my project installs it in my app target folder. How do I install these features correctly?

[Glytzhkof]

I believe the application folder is the right location for these files. This is the new style of installation designed to isolate applications from each other so they can use different versions of MFC easily.

Is this correct? Surely it defeats the whole object af having shared DLL's. After all Microsoft install ATL/MFC in the WINSYS folder.

This is correct. The goal is to avoid shared DLLs where possible. The disk space requirements for duplicate DLLs is less than the trouble caused by shared DLLs ("DLL Hell")

[Glytzhkof]

This does indeed eliminate the idea behind shared DLL's, but people now have lots of disk space and hence it is considered acceptable to duplicate these runtime files for all applications. Not sure if you can statically link to these dll's to get rid of the dependency in your scenario.
