EOS400D Utility Error

I used the app. CD (Utility, ZoomBrowser and Dig. Ph.Pro) succusfully on Windows XP, no problem downloading. Utility opened as a black window, giving download choices. I've just installed on a new pc, running Vista, and all works except Utility. Plugging the camera in brings an AutoPlay window... when I choose "Download using Canon Utility" it gives me a "Camera not recognized" message. It does seem to work if I choose the "Download using Windows".... but that is not how its suppose to go... am I wrong? Any help will be great! Thanks.

Re: EOS400D Utility Error

I too had the "Camera Not Recognized" problem, until I finally figured out what was causing it.

Yes, I uninstalled and reinstalled the software. I downloaded the most up to date EOS Utility. Blah-blah.

All to no avail.

Then, it struck me.

I have a PC motherboard with several USB ports: 4 on the rear panel and a 2 on the motherboard connected to the front panel of the PC. A couple of years ago, I blew a motherboard by connecting to one of these ports.

I had a 7-port USB hub for all my stuff (printer, cell phone, GPS, label printer, weather station, 2 monitors with built-in hubs) so I began plugging my camera into one of the USB ports on the monitor, meaning camera to hub to hub to PC to avoid the possibility of zapping the motherboard again somehow.

Today I realized that's about when the "Camera Not Recognized" problem started so I plugged the camera directly into the PC and the EOS Utility worked fine.

To make a long story short, try plugging the camera directly into the PC without any intervening hubs.

Good luck.

Re: EOS400D Utility Error

What you need to do is to go and download the latest driver updates from the Canon Website. I had exactly the same problem, and I now downloaded the latest updates for the Utility, and its working 100%.

Re: EOS400D Utility Error

check on the canon website for updated software to install the utility

often new versions are released and are freely available to download off their site
look for your camera model and check the links to download

some new cameras sold today still dont have the applications shipped with the unit
the website is the best place for the latest versions

otherwise use a third party application to transfer the images
picasa by google does a good job too

I have bought a canon EOS 300d camera with out cd. bt when i plug my camera to my computer nothing happens .i tried to do download dpp bt all i fine is dpp updater e.t.c . i have windows xp in installed ....

The updater does not need to have a previous version installed, it will install the stand alone program. However DPP is not the program you need to connect to your camera, what you need is EOS Utility. That is also availible on the Canon website.

What you can actually do is download the Zoombrowser which you can use to transfer the pictures in your camera on to a computer. The link to where to download the software is below. Once you're in the website, just choose your computer's operating system (XP, Vista Windows 7, Mac, etc.) then download the zoombrowser. There are other softwares for your camera on the said site which you might want to download as well.
Hope this helps.

Canon zoombrowser Ex downloading problem

The sd1000 manual says that you will get this error when you have too many pictures on your memory card (aprox 1000). I am not sure how many I had on my 2GB card but it was a lot. I deleted about 50 - 100 pictures and then it started working again and the new pictures downloaded to the computer.

Canon zoombrowser Ex downloading problem

Try updating the Zoombrowser software.

If you have a connection to the camera, go into my computer and get images directly off the camera using scanner and camera wizard, microsoft's default program. This will at least allow you to transfer your images until you can resolve the software problem.

If you have no connection to the camera via your computer, you need to try some other troubleshooting steps to get a connection. I will post those below in the next post.

Canon PowerShoot A80, error no camra found

Unless you REALLY must use Zoombrowser for some reason, why not simply 'read' the SD/CF Card direct on your PC ?

(you can buy a USB multi-media card/reader writer for less than £10 ...)

Cannot Download pictures from camera to computer

There are numerous solutions for importing digital pictures from your camera to your hard drive. You can use Windows Explorer. By doing this, u maintain complete control over where ur digital images are stored on the computer. If you prefer to use an external application, Google's Picasa remains the best solution available. In addition to being a convenient way to manage your images, Picasa also includes common photo editing functions, supports some of the best photo organization works with low level photo data from your camera, and assists in uploading images to the Web or creating slideshows on your local system. Picasa uses the timeline features that shows when images were taken in relation to all your other images (which only works if your digital camera is set to the correct date). Picasa is free for Windows 2000, Windows XP, and Linux.
