com.apple.WindowsContacts.client_main.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like com.apple.WindowsContacts.client_main.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like mighost.exe - to follow. These files were created so that multiple programs (eg. CopyTrans Drivers Installer) could share the same com.apple.WindowsContacts.client_main.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message.
