How to  connect a 20Da and run EOS? Does the computer need drivers for the camera? The camera shows up in Device Manager and indicates it has no drivers installed.

Canon no longer supports DIGIC II cameras like the 20Da. For this reason they have never released a 64-bit low level driver for them. This means that if you are running a 64-bit version of Windows, there is no way that you will be able to connect BYE to your camera. If your version of Windows is 32-bit then all you need is a 32-bit kernel level plug-and-play driver. Then in BYE you must select the "Canon 210" version of the SDK to use for managing the camera.

The camera is so far out-of-date that getting a driver could prove a challenge. You may be able to install the Windows XP driver on a newer version of 32-bit Windows, perhaps as new as Windows 8, but I am not sure. Some people have been successful, and some have given up. O'Telescope cannot provide that driver since it belongs to Canon.

your computer needs to be 32 bits.

you need to install the drivers that came on the cd with the camera.  Usually, Installing the software EOS Capture as it was called then may also install the drivers.
