Guide to installing Canon CanoScan LiDE 35, 50 and 60 on Mac OS X 10.8. Mountain Lion:

FIRST PART: DELETING OLD LiDE DRIVERS AND SOFTWARE

• If this is the first attempt to install the scanner, skip this part

• Trash the following files/folders from these folders:

HD:/Library/Image Capture/Twain Data Sources

delete the CanoScan CanoScan XXXX.ds file

(Make note of any other files that may be in this folder. If other files are present, move them to the desktop for now. Then place them back after successfully using the scanner.)

HD:/Library/Preferences

delete the 'CanoScan XXXX' folder

HD:/Users/Shared

delete the folders containing the name CanoScan, or starting with CNQL.

HD:/Applications

delete the CanoScan Toolbox Application

HD:/Users/YOUR-MAC-USERNAME/Library/Preferences

delete any items named "CanoScan Toolbox"

• Restart your computer, then empty the trash

SECOND PART: MAKING YOUR SCANNER WORK

• Make sure your scanner is well connected

• Download the right driver depending on your Model. Also download the Scanner Software. Copy the filenames and search them via Google. Make sure you download the Canon files from an official Canon domain.

CanoScan LiDE 50 and LiDE 35 work both with the 35 driver:

lide35osx7721en.dmg

CanoScan LiDE 60 driver:

lide60osx11131en.dmg

VueScan Software:

http://www.hamrick.com/#download

VueScan 9.2 (or later) x32 for Mac OS X

Alternative to VueScan: CanoScan Toolbox. I prefer VueScan.

Try your luck with Version 4 or Version 5.

CanoScan Toolbox 4: cstbosx4934ej4.dmg

CanoScan Toolbox 5: cstbosx5014ej4.dmg

• Open the downloaded driver file (lide35osx7721en.dmg or lide60osx11131en.dmg)

• and Double-click the ScanGear file, install and restart when prompted

• Open the downloaded VueScan file (vuex3292.dmg) and drag the VueScan application to the Mac Applications folder

• Open the VueScan application. The scanner should be recognized automatically.

(Alternatively try and install CanoScan Toolbox 4 or 5)

I assume you running some version of OS X; you did not specify.
A .exe file is a Windows executable (program). It will not run in the Mac OS unless you have Parallels. (Don't feel bad; the Windows people can't run anything for Mac.)
You should be able to double-click on a dmg file and have it mount as a virtual disk drive. First, go to the Finder Preferences and make sure the External disks are included in the items to be shown on the Desktop. If you don't get a new Finder window when you try to open a .dmg file, check your desktop for the disk image icon (it looks like a picture of a white USB external floppy disk drive without a slot on the front). Open that and you should see the files.
