Concerning web cam software

[Thumpit]

Will EOS REBEL T2i be listed as compatiable with Cannon web cam software .. 

EOS Webcam Utility Beta Software

If so which software would be the correct one   or is there any software I can use to utilize my camrea as a webcam?

Many cameras that are not listed as being officially supported seem able to work with the Webcam Utility.  If your camera supports video and remote shooting via USB and the EOS Utility, then odds are good that your camera may work.

I suggest that you install the latest version of the regular EOS Utility prior to installing the Webcam Utility.  I suggest that you try downloading the Utility from any supported camera.  It seems like there is actually only one version of the software being used by all supported cameras.
