How can i find the driver for the A400 for windows 7?

What does your computer say about it? Does it pop-up a window that says something?

Having gone over a month without a response to my query, I assume my suggestion to use a card reader eliminated the need for a driver.

I found the official support page for your camera (Samsung Digimax A400).

Click here and you will be taken to the website. Links are available for manual, driver and software.

Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ...

Here are some things that you can do to try to correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty, or if repair costs close to the value of the camera, they're worth a try. And for the A400, have actually had a lot of success with these, especially Fix #7.

Find the Software disk for the PC and install it. Make sure the camera is off, then connect the usb cable. Then turn the camera on in the playback mode.

no problem, go to the website: http://www.samsung.com/uk/support/download/supportDownMain.do
and follow the instructions on screen to find your camera and it will give you an option to download the drivers and other software avalible for your camera! (also worth doing this when you get home to make sure you have all the upto date drivers!!)

Drivers and manuals you can get HERE.

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:

1. 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.
   
2. 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.

Forget the hassle of trying to get the camera linked to the pc with software etc....

Much faster transfer of photos and no hassles with a usb card reader works every time 'no drivers' to mess with.....

Next time you get it running, right click my computer>properties>hardware tab>device manager and look for your monitor on the 'Monitors' '+' sign and right click>delete. Also check 'Display adapter' see if the correct driver is displayed. Re- boot and let Windows re-install monitor driver(it should list it as 'Sony')
