How to Update Device Drivers

There are two ways to update drivers.

Option 1 (Recommended): Update drivers automatically — Novice computer users can update drivers using trusted software in just a few mouse clicks. Automatic driver updates are fast, efficient and elimate all the guesswork. Your old drivers can even be backed up and restored in case any problems occur.

Option 2: Update drivers manually — Find the correct driver for your Scanner and operating system, then install it by following the step by step instructions below. You’ll need some computer skills to use this method.

Option 1: Update drivers automatically

The Driver Update Utility for Acer devices is intelligent software which automatically recognizes your computer’s operating system and Scanner model and finds the most up-to-date drivers for it. There is no risk of installing the wrong driver. The Driver Update Utility downloads and installs your drivers quickly and easily.

You can scan for driver updates automatically with the FREE version of the Driver Update Utility for Acer, and complete all necessary driver updates using the premium version.

Tech Tip: The Driver Update Utility for Acer will back up your current drivers for you. If you encounter any problems while updating your drivers, you can use this feature to restore your previous drivers and configuration settings.

Double-click on the program to run it. It will then scan your computer and identify any problem drivers. You will see a results page similar to the one below:

Click the Update button next to your driver. The correct version will be downloaded and installed automatically. Or, you can click the Update All button at the bottom to automatically download and install the correct version of all the drivers that are missing or out-of-date on your system.

Before updating, use the built-in driver backup feature to save your current drivers to a specified folder. Use this backup folder to safely restore drivers if necessary:

Option 2: Update drivers manually

To find the latest driver, including Windows 10 drivers, choose from our list of most popular Acer Scanner downloads or search our driver archive for the driver that fits your specific Scanner model and your PC’s operating system.

If you cannot find the right driver for your device, you can request the driver. We will find it for you. Or, try the automatic option instead.

Tech Tip: If you are having trouble finding the right driver update, use the Acer Scanner Driver Update Utility. It is software which finds, downloads and istalls the correct driver for you — automatically.

After downloading your driver update, you will need to install it. Driver updates come in a variety of file formats with different file extensions. For example, you may have downloaded an EXE, INF, ZIP, or SYS file. Each file type has a slighty different installation procedure to follow. Visit our Driver Support Page to watch helpful step-by-step videos on how to install drivers based on their file extension.

Acer scanprisa 640ut driver windows 7

I’ve had quite a few problems to get the Acer ScanPrisa 640P to work with WindowsXP. Unfortunately the only sites dealing with this problem where russian, and I don’t speak any russian at all. Thanks to the help of a friend in irc (/me waves to Daan) I finally managed to make the whole thing work.

So for future reference, and to help other non-russian speaking people with the same problem, here’s how I did it:

Note: This worked for me. I can not guarantee that it will work for you as well, but it’s definitely worth a try
I’ve found some extra info about the problem on a different russian site: http://www.computery.ru/upgrade/faq/. g_098.htm#Acer

ok now for what you have to do.

(Make sure your Parallel Port is set to EPP in your BIOS)

1. COMPLETELY uninstall the MiraScan dirver:
First go to «add/remove Software» under windows and remove it from there.
Then go to your ‘windows\twain_32’ directory and remove the mirascan folder in it (or what is left over from it).
Now open regedit and clean your registry from all ‘mirascan’ entries, especially the ones in the twain section.

2. When you’ve done that, copy all the files in your ‘..mirascanv3424p\TWAIN’ folder to the two following folders:
first to ‘windows\system32\dllcache’ (otherwise windows will restore the dlls when you overwrite the ones in the windows dir)
then also copy them to your ‘windows’ dir
(always overwrite the existing files!)
Now a windows-dialog will propably pop up and ask you if you really want to do this. blahblahblah. Just ignore it. YOU HAVE TO KEEP THE NEW DLLS IN THE WINDOWS FOLDER!

3. reboot your system

4. now start the mirascan-setup. choose CUSTOM INSTALL and only install the first two things (can’t remember what exactly they were called), but do _NOT_ install the EPPMINIDRIVER thing!

If you now try to «acquire» the twain source with a program, you should get a «scanner not found» error. At least that is what I got at this point.

5. go to the windows device manager and remove the ‘color flatbedscanner’ if it’s there. If it’s not there, this should be ok too. It was there when I did it.

6. do the same thing you’ve done under point 2 AGAIN. In other words, overwrite the dlls in the windows folder with the ones in your mirascan\twain dir again. (no idea if this is really necessary, but it have done it.)
then reboot your system.

8. start the mirascan-setup again. choose CUSTOM INSTALL, but this time only install the last thing called EPPMINIDRIVER or something. untick the other two things which you should have already installed under step 4.
when the installation is done, use the windows wizard to add the EPPSCANNER ‘color flatbedscanner’ and reboot your system for the last time.

Congratulations, your scanner should work now. Don’t blame me if it doesn’t, but write a hate mail to ACER aka BENQ instead 😛
