Most DLL errors are caused by the "registry database" of Windows.
This is a storage facility for all the files, settings and options that Windows uses to help it run. The problem is that there is a large list of DLL files your software uses to run - this list is highly important but is continually being damaged, causing the errors you're seeing. You can easily fix this problem by using a "registry cleaner" program to repair any registry errors your system has.
