As a workaround, please try to register manually wiaaut.dll by doing the following:

Copy the file wiaaut.dll in iCopy folder to C:\WINDOWS\system32\ (if not already present)
Run a Command Prompt with adiministrator rights
Type cd C:\WINDOWS\system32\ and press Enter
Type regsvr32 wiaaut.dll and press Enter
