New Side by side on my piano keyboard oh lord why don't we...
Windows XP and later have something called Side-by-Side Assemblies:


Starting with Windows XP, multiple versions of side-by-side assemblies can be used by applications running at the same time. Manifests, and the assembly version number, are used by the loader to determine the correct binding of assembly versions to applications.
...
When an application calls to load the DLL, the side-by-side manager determines whether the application has a version dependence described in a manifest. If there is no relevant manifest, the system loads the default version of the assembly.

DLLs did make some sense in saving memory and load times on slow, memory-constrained machines. But once MS's APIs got ungodly complex, they tied applications into the OS, etc., etc., then it was guaranteed to break. This [link|http://www.geek-central.gen.nz/peeves/shared_libs_harmful.html|rant] from 1998 makes the point pretty well.

Like many of these things, it seems to be [link|http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=5708811.PN.&OS=PN/5708811&RS=PN/5708811|IBM's fault]...

The universe is 98 percent hydrogen and helium... and I'm rather fond of the other 2 percent.
