Installing canoscan Lide 20/Ld 30 driver into mac 10.6.8

Go here, Worked for me.
http://blog.thewheatfield.org/2009/10/12/canon-canoscan-lide-20-on-os-x-10-5-8/

I found Vista drivers here.
http://software.canon-europe.com/products/0000466.asp

I was able to install the CanoScan Toolbox by doing the following: MacIntosh HD --> Library --> CFMSupport --> Get Info. Under 'Sharing & Permissions', I added my name & changed 'Read only' to 'Read & Write' .

Problem now: I can't install the LIDE 30 Scanner Driver. I clicked on the downloaded driver & a box opened. I clicked on ScanGear CS Installer, but that didn't work. I then clicked on 'Into Plug-In' --> ScanGear CS 7.0X --> Choose Application --> CanoScan Toolbox 4.1 --> Plug-Ins, but couldn't continue as the 'Open' tab was greyed out. What should I try? Any suggestions would be appreciated.

I found this scanner at a garage sale today, and had trouble finding this info myself. Finally stumbled upon this site ( http://cadwell.livejournal.com/39545.html )

I'm using it on a Powermac G5 but both the driver and toolbox app say they are univeral binary. Hopefully this gets you up and running too:

CanoScan LiDE 30 on Mac OS X 10.5
This technical help may seem completely out of place on this art blog but after scouring the internet for 3 hours trying to set my 6 year old scanner up on my new MacBook, I found this info half way down a lengthy comments section of a random blog. So I thought I'd post it here (slightly altered) as a message in a bottle to anyone else in need of it.

How to set up CanoScan LiDE 30 on Mac OSX 10.5
STEP 1:
http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=351&modelid=6623
STEP 2:
Select MAC OS X
STEP 3:
Download BOTH:
LiDE 20/LiDE 30 Scanner Driver Ver. 7.0.1.1aX
(Mac OS X)
lide20lide30n670un676un1240uosx7011aen.dmg
CanoScan Toolbox Ver. 4.1.3.0X
(Mac OS X)
CSTb4130MXE.dmg.gz
STEP 4:
INSTALL CanoScan Toolbox Ver. 4.1.3.0X
STEP 5:
INSTALL LiDE 30 Scanner Driver Ver. 7.0.1.1aX . Make sure Applications>CanoScan Toolbox 4.1>Plug-Ins is selected as the install location.
STEP 6:
You will be asked to RESTART. You should.
STEP 7:
When you run CanoScan you can choose Photoshop as the default program to open the image in once it has scanned. You do not need Photoshop to open using Rosetta for this to work.
NOTE: If you want to scan directly from within Photoshop CS3, you need to copy the driver 'ScanGear CS 7.0X' which is found in Applications>CanoScan Toolbox 4.1>Plug-Ins into the photoshop pluggins folder, Applications> Adobe Photoshop CS3>Plug-Ins>Import/Export. You also need to open photoshop in Rosetta mode. Apple + I on the photoshop icon and select 'Open using Rosetta'. I would not recommend using this method though.
STEP 8:
Go to System Preferences>Accounts>Login Items and remove both of the following:
N067U_ButtonManager.app
N124U_ButtonManager.app
STEP 9:
SCAN.

(at least it worked for me, OS X 10.5.5 / LiDE 20)

Select your operating system and download the driver "TWAIN Driver - LiDE 20 Scanner Driver Ver. 7.0.3.1a_xp" and then download the software "Canoscan toolbox" ...here is the link:
http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=351&modelid=6624

here is the driver link for ur scanner download & enjoy

Download the installer here:
http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=119&modelid=6623#DownloadDetailAct

try installing software with superuser credentials.

This seems to work with fink/xsane or the canoscan drivers from their site, but neither as well as you might like.
