When I Install The Driver On 32-Bit Version Of Windows Using The “Locate And Install Driver Software (Recommended)” Option, The 64-Bit Driver Is Installed And The Pen-DTU Does Not Work. Why?

Windows prefers digitally signed drivers over drivers that are not digitally signed. Due to restrictions in 64 bit windows, all 64bit drivers must be digitally signed. In order to install the correct driver, you must re-install the driver manually. Go to the Windows Device Manager, find the “GCS PENDTU USB DEVICE” section then Right Click the [WDF:KMDF] driver and select “Update Driver”. Click on “Browse my computer for driver software”, then click on “Let me pick from a list of device drivers on my computer”. Click on “Have Disk” then “Browse” buttons. In the “Locate File” window, navigate to your TopGuard CD or Installation Folder and find the “USB_GCSPENDTU_DRIVER” folder, then go into the “GCSPenDtuUSB 32bit” folder. Click on “Open” then click OK. Click on Next and complete the driver update wizard.
