You can dynamically load libraries in Windows programs, but methinks that it 
also requires writing wrappers around all functions. Wrappers get the address 
of the function and then do the call. You can also resort to calling function 
by address (function variables) and first initialize those upon loading of 
the library.

Windows generally looks for .dlls in the path and executable's own directory. 
I don't think it can be made to look anywhere else, although what you can do 
is simply copy or move the dll's to \windows or \windows\system. That's what 
all applications do to make their dll's visible. You can write a short 
program to remove them upon uninstall, if you're not using stock installer 
like Windows Installer (free from M$) or InstallShield or somesuch.
