No it is not a monthly contract. You will be charged for this request only and too only if you are satisfied the service.
I am providing you with the necessary software for your scanner but for that I need to know that your system is 32 bit or 64 bit.
To find out if your computer is running a 32-bit or 64-bit version of Windows in Windows 7, do the following:
Open System by clicking the Start button , right-clicking Computer, and then clicking Properties. Under System, you can view the system type.
