This is just a FYI as I had just managed to get my own Acer 320U scanner up and running in Win8.1 x64. This driver also works in Win7 to Win10!
The same drivers work for the following abandoned Acer/BenQ scanner models:
x86 / 32-bit: x86.zip
x64 / 64-bit: x64.zip (replace the INF with this newer one here)
[2015-09-11] x64 with scan size fix by McReall & newer INF: x64.zip
All drivers are unsigned and this poses a problem if you are using x64 as you will either need to completely disable the driver signing check or sign the x64 drivers yourself. I recommend the latter as it's actually quite easy! Simply follow this guide here.
Some pointers:
To scan in Windows 8 after driver installation, simply go to Devices and Printers, right-click your scanner and click Start Scan. You can also use the Metro 'Scan' app, although previewing scans return a very blurry image.

Some pointers:
- The tools you need (makecert, Inf2cat, signtool) can be found in the Windows SDK and the Windows Driver Kit. You don't need to install everything! Just check the "Tools" in both the web installers will do.
- If you cannot download the SDKs due to filesize (~2.2GB), I zipped the 3 tools and you can download them here. But please download from Microsoft whenever possible.
- When making your own cert using makecert, add the -pe parameter so that you can export the private key of the certificate later (useful for installing your own signed drivers again on a different PC in the future! To export, simply right-click your certificate in the MMC snap-in)
- You need to use the newer INF in the Pastebin as the old one will not sign or validate correctly.
