Not able to install DS-330 driver in Windows 7 (32\64 bit) OS

You do not need any driver for the ClassPad 330. You connect it through the USB port. If it came with the ClassPad manager 32 bits application, just install it. Windows 64 bits system have a 32 bits subsystem to run 32 bit applications.

Usted no necesita ningun controlador driver para la ClassPad 330. Se conecta a traves del puerto USB. Si viene con el gestor de aplicaciones de 32 bits ClassPad, solo lo instale. Sistema Windows de 64 bits tienen un subsistema de 32 bits para ejecutar aplicaciones de 32 bits.

you should be able to install the 32bit driver normally.

go to device manager and click on update driver once their point towards your 32bit driver

Open the printer and scanners folder an delete all the devices (Brother Printer, Brother Fax, Brother PC-Fax if installed). Point to device an right click the mouse button.
Restart the computer.
Download the software from Brother Solutions Center. Download the whole suite not just the drivers. Make sure you select the software that is compatible with your version of the OS :Windows 7 32 bits, Windows 7 64 bits, Windows 8 32 bits, etc.
Install the software. If you are going to use a USB cable to connect the MFC to the computer, install a local USB printer. If you are going to use Ethernet network cable, install a wired network printer, and if wireless connection then install a wireless printer.
If you have problems finding or attributing an IP address to your printer (for Non-USB connections) there is Brother program that helps you attribute an IP address. You will find it on the same page as the software suite on Brother's site.

Hope this will help someone else:
InWindows' Device Manager (devmgmt.msc), the SXUPTP driver was showing as disabled.Windows gave a warning that the device was known to have stability issues. Ifound out that SXUPTP is a driver from a company called Silex. Silex makesnetwork USB hubs, so I assume that the Belkin hub is a rebranded Silex hub.

In order to update the Silex driver follow these steps:
1. Close the Belkin network hub's tray application.
2. Download the latest version of SX Virtual Link(sx-virtual_link_win_3120.zip).
3. Extract all of the files.
4. In Windows Explorer, navigate to sx-virtual_link_win_3120\s-33a3120\Files\Bin\Sxcsapi\WinVistaX64if you are running a 64 bit OS, orsx-virtual_link_win_3120\s-33a3120\Files\Bin\Sxcsapi\WinVista if you arerunning a 32 bit OS.
5. Right-click on "Sxuptp.inf" and select "Install" fromthe menu.

The driver will be installed and the warning icon in the device manager shoulddisappear. You may need to reboot for the changes to take effect.

do you have programs files (86) in your PC "C" drive menu menu? If yes that;s where yiou should install the software. That's because it;'s a 32 bit on a 64 bit.

is the motherboard 64 bit compatible? usually a 32bit system will not accept a 64bit OS. missign a motherboard driver it sounds like..check your control panel device drivers for errors

Download your driver from here driverupdate us . Download the software (for free), scan for the required driver and update, It will take 2 mins. Hope this was helpful. cheers
