You can not simply install drivers by copying the files. Installation of a driver involves lots of more complicated steps than just copying files such as creating registry entries, services, event logs, and so on. Simply copying a file tells Windows nothing about the driver.
What you can do, is to copy the individual files as necessary (for example in the dialog below that prompts you for the location of a driver file). That said, the necessary files may not all be in the same place (
%systemroot%\System32\Drivers), and could be in theProgram Files
folder,%systemroot%\Help`, and basically anywhere else the manufacturer thought its files belonged.
It is best just to use a copy of the original driver installation program, but if you don’t have Internet access or the CD, then maybe a copy of the driver installer has been cached. Look for an executable (
.exe) or Windows Installer file (
.msi) in the relevant
Program Files folder and
\Windows\Installer (perhaps do a file-search depending on the device manufacturer’s name).
