Mustek ScanExpress A3 USB Scanner - Windows 11 Driver

Posted 14th Nov 2022
I'd like to use an older A3 scanner that I own on my Windows 11 PC. The model is a Mustek ScanExpress A3 USB.

I've been onto the Mustek website and their drivers go up to XP, although there is a text file in the downloads folder which says it will work with Windows 10 - you need to 'Disable driver signature enforcement'
Index of /pub/new/driver/ScanExpress A3 USB/ (

I've done that but the driver still doesn't work. I then did a Google search and there is a product called VueScan ( who apparently use their own drivers for older scanners.
I downloaded VueScan and my A3 scanner worked on my Windows 11 computer.'s a demo version only and you have to pay £25 for the licensed version.

So...there must be a way I can get Windows 11 to recognise my A3 scanner now I know it works with VueScan.
I was wondering if anyone has any ideas on how I can get it working so I can use it without the need for purchasing VueScan. Happy to use it with Windows Fax and Scan.

    Vuesan has worked with every prehistoric scanner I have ever thrown at it.

    One of my second-user Windoze boxes has "Vuescan Portable" installed and do not recall ever having to pay sub / premium.

    Even the basic edition of the paid version has limitations…tml

    My scanner is probably 20 years old now, but new A3 scanners are expensive to buy so wanted to resurrect my Mustek. Plus I rarely need to scan in A3 so it would only be for occasional scanning, hence why I'm trying to find a free way of getting it working.
