I'm experiencing the exact same problem with brand new Adobe Acrobat X. I'm using a Canon Lide 600F, running on Windows 7 64-bit.

Did you resolve this problem in Acrobat 9?

I just tried with Canon PIXMA MP780 with 64 Bit Win 7 and it worked with Acrobat X. Are you able to scan with other applications, like MSPAINT, TWACKER that use TWAIN driver?

Yes, I'm able to scan with other programs. I'm also able to scan with Acrobat X, but only using Custom Scan. All the presets are greyed out, and when I select Configure Presets, and select the twain driver I get the error about the missing SCANINTF.dll. When selecting the WIA driver I get this error:"This scanner does not support presets".

What is strange is that I have used this scanner with Acrobat 9 and Windows 7 64-bit before, and everything worked just great. Seems to me this is a problem with Acrobat X, not the scanner driver..

I'm using the latest Canon driver (12.12).

Just to let you know: I was able to get scanning using profiles working again by downgrading to Acrobat 9 Pro. Thanks for your input.

Re: Windows 7 (64-Bit) with a CanonScan 8600F Scanner

Previously I had the "scaninitf.dll is missing" error, but now after trying to re-point Adobe 9 Std to the scanner, I'm also getting "Error while interacting with the scanner: the selected scanner was not found."

Now here's the interesting part: If I create a PDF using the CanoScan Toolbox (it is pointed to "C:\Program Files (x86)\Adobe\Acrobat 9.0\Acrobat\Acrobat.exe"), and create a PDF all works fine. If I leave Adobe open to this created document, and try a 'Create PDF from Scanner' operation from within Adobe directly to create a new scanned PDF, Adobe works as it used to before this most recent Adobe update. That is, it finds and scans a new PDF just fine!

For now, I'm using the CanoScan toolbox to fire up Adobe 9.0 for creating PDF's from the scanner...and patiently waiting for an update to be pushed down from Adobe Galactic.

Erol, thanks for your post.

We must have slightly different issues. I don't have a ScanGear app on my install (just a readme and uninstall icon in the folder where it should be). This was from a fresh install from the CanonUSA site for the 8600 Win7x64 driver, Adobe RGB, and CanoScan Toolbox 5.0.

My toolbox runs just fine and in all functions. The Windows Devices and Printers Scanner icon operates just fine with no problems. All other scanner-related apps on my machine operate properly with the scanner. It is only Adobe Acrobat Std. 9.4.0.195 (core version 9.4.1) that is not operating properly. Prior versions of Adobe 9.0 used to work properly on my machine but now don't since the latest update.

I even went so far as to copy the twain drivers to the Acrobat Directory, and create an environment variable and now I get the image above:

Windows 7x64 Canon Lide600F with 12.12 drivers and CanoScan Tool Box 5.

If I try to use a Custom Scan I get this image:

Any thoughts? NE1?

Abustraan - you did it! Thank you. I added my twain driver path to the system environment path, re-booted, and all is well.

For Adobe staff - in case they ever read this thread, here are the two places this twain driver file is referenced in my registry:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\PnpLockdownFiles

and

HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Setup\PnpLo ckdownFiles

Mine was a Win7x64 OS.

Thank you again Abustraan for getting my Adobe back up and working again with my Canon scanner! Good Job!

I just re-installed the ScanGear 12.12 64-bit software from the Canon Website and here is what the readme says:

I'm having kind of the same problem.

My Brother MFC-9840CDW used to work perfect on Adobe Acrobat Pro 9.5.0

Suddenly, a few days ago it stopped working. In fact, it looks like all my Twain-driven applications has stopped working, but only my WIA works (example: Photoshop).

I have tried removing and re-installing the complete software package from Brother as well as ensured that it was the correct entries in the Registration Database.

Nothing seems to help though...

Any idea on how to manually install the Twain drivers or any other solutions?

When opening Acrobat and selecting Create PDF - from scanner - I select the Custom Scan. In the pop-up there is no scanner to be selected. It's driving me nuts!

I'm running Win 7 64-bit

Rgds

Tried that – No success.

Even tried installing the USB version of the driver – didn’t help either.

Any other ideas?

Venlig hilsen / Best Regards

Erol,

I have done more checking into Twain functionality for 64-Bit and there aren't any true 64-Bit twain drivers for Canon Scanners.

Even though the driver that I have downloaded says in the readme file that it is 64-Bit Twain compliant, it only works with 32-bit apps.

Here's another case of the same thing.  Adobe Acrobat X, gets the scanintf.dll missing with my Canon LiDE 70.  That scanner works perfectly with Acrobat 9.  I'm really getting burned out on this thing.  I NEED to scan in documents to get my home and car insurance set up, and I can't DO it with this POS!!!  Does anyone from Adobe ever read these forums?  Or are we just spinning wheels?  I paid a lot of money to Adobe for all the various stages of the CS3, CS4, CS5, CS5.5, and soon the CS6 web premium suites.  I DON'T seem to be able to get support, though!

I have

canoscan lide 600F

windows 7 x64 ultimate

adobe acrobat 10

all programs in my computer recognize the WIA side of this scanner but not the TWAIN

I did follow the instructions above for variable

I have the following folder C:\windows\twain_32\CNQ4802  which I have added to the variable enviroment Path

reboot couple of time

installed the newest drivers which are not new at all 2007-2009 date

upgraded acrobat from 10 to 10.1.3

nothing helps...

is there anything I am missing

p.s. I have an HP Envy 17 3200 with ivy bridge and  all the ports are USB 3 with newest updates from microsoft , intel and HP

oh when I type path in a CMD.exe

I get bunch of paths but non of them is the one I entered ..

how can I force the path in there?

detailed response on the steps on that

again in windows 7 x64

Hummm. I just tried a couple of things

I set up a 2nd computer that has Win 7 Ult x64 and Installed Acrobat X 10.1.3 from scratch. Installed the same 12.1.2 that I had on my other computer and got the same error. Added the 'C:\Windows\twain_32\CNQ4802' to the path statement. Rebooted and It works just fine.

As a 2nd test, I removed the 'C:\Windows\twain_32\CNQ4802' from the path statement and rebooted and the error returned. I re-added it and rebooted and it scanned okay.

Is the file 'SCANINTF.DLL' in the folder 'C:\Windows\twain_32\CNQ4802'?

Also in case you don't have the 64-Bit version of the Canon 600F they can be found here.
