Yes, that's the theory. In practice, even Microsoft refers to this as 
"DLL hell". A typical system ends up with multiple, perhaps 
inconsistent, versions of various DLLs and often there's no good way of 
knowing which version will be selected for a particular application. 
The result is that your application may or may not work right, 
depending on which version of each of its DLLs gets loaded. Unless, of 
course, your application supplies its own version of every DLL that it 
uses.
