It took me a while to find the Windows 7 64-bit driver for the XE-A506, but apparently it is located under the XE-A406 version. Eventually, this one worked for me: but don't forget to run the program as administrator (properties - compatibility - "Run this program as an administrator").

By the way, the manual was a bit unclear on how to install the drivers (for me at least). This is the whole process that actually got it working in my case:

• Go to "Devices and Printers"
• Right-click the device under Unspecified - select "Properties"
• Select the "Hardware" tab
• Open "Properties"
• In the "General" tab, select "Change Settings"
• Select the "Driver" tab
• Here the option for "Update Driver..." should be available, open it
• Select "Browse my computer for driver software"
• Select "Let me pick from a list of device drivers on my computer"
• Press "Have Disk" (sometimes this option isn't immediately available, first press "Next" in that case)
• Select "Browse"
• Head to the location where the driver (*.inf) is downloaded, something like "Downloads\SHARP XE-A406_A506 SOFTWARE - 64bit\Sharp XE-A406_A506\Setup\program files\SHARP ECR TOOL\XE-A406506 Customer Support Tool\Driver\Win64" and select it
• Press "Open"
• Press "OK"
• Press "Next". The driver should now install.
