Well, it seems I made a mistake. I installed the new Canon Imagebrowser suite of software (EOS Digital Solution Disk ver 23.0) which came with a new SLR. And I hate it, but that is another discussion. I can't get this turkey off my Mac. Or that is, I can remove it according to the instructions, but if I try to install a different Canon EOS camera software, the installation program says that the software component programs, such as Imagebrowser, are already installed. I followed the instructions for uninstalling, which is quite simple. Just drag all the files in the Canon Utilities folder to the trash, empty the trash, and restart. Sounds simple enough. If it worked! Too bad this psychotic program doesn't want to go away. My desire, BTW, is to install, or maybe I should say, re-install the earlier version that I like because it is quicker, easier to file, and simpler to use. Unfortunately, I can't re-install any earlier version of the software anymore. The Canon installation program will only proceed when it is re-installing the same version 23.0 First, I don't think it really doesn't matters which version of this software suite you are trying to get rid of because the problem also occurs with EOS ver 6.1 on both 10.4.11 and 10.5.8 I can't get rid of it either, if I want to. Second, there is no Uninstall program on the installation disks. Third, I can re-install the same version of the software, but I don't want to do that. I can also seem to "upgrade" to a later version. ("Upgrade" seems a dubious term, at best, to describe a version of what should be a simple program to download files that is less efficient than the old program. Also, I am looking at the name, "EOS Digital Solution Disk" with a bit of wry distain. I like the older versions of this program a lot. The newer versions seem less desirable.) Fourth, I have also noticed that you can't install two versions of this software on a Mac computer system, even if you try to put it on a separate drive. Having different versions could solve this problem, but that is apparently verboten. Has anyone figured out how to UNinstall Canon's EOS software successfully?
