I tried loading my older Canon LIDE90 scanner used in a PC but now I want it in my new iMac but there's no comparable driver for the 10.9. So instead - there were a few pieces of the bundled software on that Canon disc that I wanted to load. One is MP Navigator EX 1.0 which loaded fine because its apparently still compatible w/iMac while the other "ArcSoft PhotoStudio" might not be compatible. Was advised to try the 10.8 Canon scanner driver (which is Mac compatible rather then 10.9 which is unavailable) and it loaded successfully into the machine but I cannot find it anywhere and it doesn't show up in the Canon folder in "Applications." Pics below that indicate one sure success and one apparent driver success: Any help here? Thank you. This is the one (10.8) that I cannot locate on the HD This one I have OK.
