I have looked every place I can think of and need help. At some point the Canon downloader (MCU?) started coming up when I attache a card reader. I've been using Bridge to download and Canon software was not starting. Now I'm using LR3 and I can't stop Canon.
I would prefer not to rename the software to stop it.
Can anyone help me? (With the Canon downloader - I need all kinds of help but tonight this has bubbled to the top).
