Clone 3 Question

I can use Clone on Win2000 pro without any problems whatsoever. If I upgrade to, reading the image is ok but I then get a message “cannot get exclusive access to drive” or something like that. If I chose the “ignore” option the copy burns fine. Does anyone have any ideas how I can cure this problem?
Also, what was the last version of Clone 3 and where can I download it?

For Clone CD 3, I belive that is the last one.

You can prevent the excluse rights errors by disabling the autorun setting for you drive or by letting CloneCD closing your drive’s tray. Open your drive, insert the disc, press the read button in CloneCD and your tray will be automatically closed. The error is caused by Windows trying to access your drive and the discs contents and thus CloneCD hasn’t got exclusive rights.
