Extract CUSB03C.dll from .zip. We recommend that you extract CUSB03C.dll to the installation directory of the program that is requesting CUSB03C.dll.
If that doesn't work, you will have to extract CUSB03C.dll to your system directory. By default, this is:
C:WindowsSystem (Windows 95/98/Me)
C:WINNTSystem32 (Windows NT/2000)
C:WindowsSystem32 (Windows XP, Vista)
C:WindowsSystem32 (Windows 7/8/2008r2/10/11)
C:WindowsSysWOW64 (Windows 7/8/2008r2/10/11)
If you use a 64-bit version of Windows, you should also place CUSB03C.dll in C:WindowsSysWOW64
Make sure overwrite any existing files (but make a backup copy of the original file).
Reboot your computer.
If the problem still occurs, try the following:
Open Windows Start menu and select "Run...".
Type CMD and press Enter (or if you use Windows ME, type COMMAND)).
Type regsvr32 CUSB03C.dll and press Enter.
