Here are the steps to take.
1. Establish whether or not you have a connection
between your camera/computer by going to your start button, control panel, system
tab and device manager. The camera must be powered on and in playback mode (should automatically go to playback mode when connected, camera's screen should go black if there is a connection). Make sure you have a fully or nearly fully charged battery in your camera.
2. Once in device manager, look under Imaging Devices. If your camera is properly connected it should show up as Canon Powershot
SD800. If it shows a yellow exclamation point, there is a driver issue, and even if it doesn't show a yellow exclamation point, you may want to update your driver anyway by right clicking and having the system search automatically for driver updates. If download of driver begins, great...once finished, restart camera and your problem may be resolved. There may also be a driver available for download on the Canon website if you log onto www.powershot.com
and go to the download library, select your camera from the menu and select your operating system from the dropdown menu. Look for TWAIN or WIA driver.
3. If there are any other imaging devices, you may have to temporarily disable them to avoid conflicts.
4. If you have any other imaging software running, exit or close the program in your system tray (down by your clock in the right hand corner of your computer's desktop
5. Try again to connect.
6. If you are on a desktop, try a rear usb port vs. a front port. You can also try a different port on a laptop
. After each change, try restarting camera to establish connection.
7. Go to start/My Computer and look for the icon for your camera...you will be able to download images even without Canon software
loaded onto computer so this is not a software issue if you have no hardware
connection. If you see the icon, right click on it and choose Get or Import pictures. From there the default Microsoft scanner and camera wizard should launch and you will be able to import your images.
8. If still no connection, try going to Start/Run and type in services.msc here you are looking for 4 services to be running. Check under status of each service and make sure it reads that each of these services are started.
- Canon Camera Access Library 8 (if Canon software loaded)
- SSDP discovery service
- Universal Plug and Play Device Host
- Windows Image Acquisition
Once all of these services are started on your computer, restart camera once again. If any of the last three services are not on your computer or are not started, connecting will be a problem.
If all of these steps fail, try purchasing
an SD card reader from your local electronics store for around $12 and download images from there. Canon also offers lifetime technical support
for your Powershot, so give them a call if none of these steps work or if you would like someone to walk you through it.
Best of luck to you!
