Hi there i own as iBook G4 and cannot get the software for the canoscan Lide20 to install. I have been on Canon's website and downloaded a recent copy of the drivers but i can't seem to find the application to open the file and run the setup. I have been to numerous places and ultimately i get the same result. I can download the software but i can't find the application on my MAC to run it. I am running Mac OSX 10.4.11 and i purchased my MAC in November 05. The scanner i am trying to use was the scanner i had for my old PC which i purchased in Sep 03. I don't have the discs anymore but i'm sure that just downloading the software will fix the problem if only i could get the thing to open and run setup! I had the same problem with my old printer and i ended up buying a new one but i would prefer not to do that as i am short of funds and i am sure i am being blonde. When i download from canon it tries to open with Quicktime but won't as it says is not a movie file. And when i download from other sites it tries to open it with WORD!!! I can't find anything else on my MAC that would do the job. Any help please!!! It's really important that i scan in some documents ASAP and send them away. Thank you in advance.
