In order to get rid of the error, you have uninstall the driver, update your operating system with updates from Microsoft (see below for instructions) and follow these suggestions:
- Best method, copy the photos to the computer by connecting a card reader to the computer and plug the SD card into the card reader and transfer using your favorite software (like Picasa) or through My Computer.
- Drivers are not required for the A400 and Windows XP. So you can plug in the camera, without drivers and it should work. This appears to be the one that's not working, You need to un-install the drivers and either reinstall, try updated drivers from the links below, or don't use the drivers.
This information is in the manual on page 96. See this link
for the manual.
See this link
for details about the WIA driver.
About the error "driver update failed" rea
I personally have stopped altogether trying to get the drivers and software installed because they can cause more problems. I just transfer using a card reader.
If you want to use the software that comes with the A400, it's best to install ZoomBrowser, then you will need to follow to this link to get the update to this software.
Once this is done, reboot your machine to make sure the system is then up-to-date.
Make sure you have also updated your machine with Windows Updates. This is done by opening Internet Explorer and clicking on Tools | Windows Updates. Follow the links at their site to update your machine.
