I don't know how other apps do this, but afaik giving each app there own 
private copy can still cause problems.
If a dll with the same name as the one you are trying to load is already 
in memory, Windows will use the the one already in memory.
When the version thats in memory is to old for the app you are starting 
it will crash because of the version mismatch.
