    Hi,
    I have a Canon CanoScan 8800F flatbed scanner that I used to be able to use with my old computer running Windows XP. I’m now running Windows 7 Professional 64bit and can’t get the scanner to work with the Canon software (MP Navigator EX 1.07). When I try to scan I get a “scan failed” message. I spent half an hour on the phone with Canon technical support and they finally gave up and said it’s something wrong with my computer.

    Another clue is that when I try to scan with PhotoStudio 6 I get an error message that says “TwainExe.exe-System Error: ?OpenIopManager@Iop_Manager@@UAEHPADAAVFG_String@@@Z could not be located in the dynamic link library IOP.dll”.

    And yet another clue: I can scan just fine using Omnipage SE4, but it doesn’t have provision for scanning slides which is what I really want to do.

    Any suggestion on which piece of software is responsible for this and how I can fix it would be greatly appreciated. Is it a missing dll? a corrupt file? a registry error?

    I’ve run numerous registry scans and fixes, downloaded new versions of everything I can think of, and manually installed some dlls in the PhotoStudio directories which changed the specific description of the TwainExe error each time which suggests to me that some of these missing dlls were required, but now nothing I do changes the symptoms and I’m really in the dark on this.

    You have a couple of options, but I’m going to recommend one that has a high chance of success, if you still have access to your old machine…

    This site provides access to a free system that allows you to convert your old physical PC to a virtual machine. You’ll probably need access to a large external USB drive to make this work, since the finished result will be the same size as the amount of disk space used on the old system:
    http://www.vmware.com/products/converter/overview.html

    The same company provides a free player to run that virtual machine:
    http://www.vmware.com/products/player/

    So, you take your old XP system, turn it into a virtual machine (basically a set of large files) and then you run your old PC as an application on your new PC. This will allow you to run all of your old applications and drivers. You’ll be able to plug your scanner in and use it on the same XP system. It’s easy to get the VM to share the host disk, so passing files back and forth won’t be a problem.

    Unfortunately, any other option requires knowing a lot about how Canon’s TWAIN driver works, which is vendor specific knowledge. You also need to understand the difference between 32-bit vs 64-bit Windows. If you really have to investigate that path then you’ll need to learn about file and registry redirection, the difference between “System32” and “SysWOW64”, “Program Files” vs “Program Files (x86)”, and the use of OS compability mode.

    At that point I’d recommend getting a scanner that’s rated for your OS…

    There seems to be some question of how compatible the 8800f is with Windows 7…
    http://www.microsoft.com/en-us/windows/compatibility/win7/CompatCenter/ProductDetailsViewer?Name=Canon%20CanoScan%208800F%20USB%20Scanner&vendor=Canon&Locale=1033&ModelOrVersion=2168B002&BreadCrumbPath=8800f&Type=Hardware&tempOsid=win7

    Assuming Canon says definitely that the 8800f is 100% compatible with your edition of Windows…

    I would download & try IrfanView (http://www.irfanview.com) and see if it can scan from your 8800F. IrfanView is free, has been around for years, is used by millions of people worldwide, and uses TWAIN for scanning. I am not affiliated in any way with IrfanView or its author or publisher.

    If IrfanView can’t scan from your scanner, then there is a problem with your scanner or its TWAIN driver. You may need to go back to Canon tech support. You may need to uninstall the scanner, remove the driver, manually strip all traces of the driver, turn off any anti-virus, re-install the driver following Canon’s directions *exactly*, etc. etc. you probably know this drill.

    BTW this error (“TwainExe.exe-System Error: ?OpenIopManager@Iop_Manager@@UAEHPADAAVFG_String@@@Z could not be located in the dynamic link library IOP.dll”) suggests that the Canon ScanGear driver is broken, since that problem is internal to the ScanGear driver.

    If IrfanView can scan from your scanner then (a) you certainly have a working TWAIN driver+scanner combination and (b) the problem is almost certainly in the non-working application(s).

    If I was a betting man what you describe is a driver issue. 32 bit and 64 bit is different and it does require proper drivers for each Windows operating software. I can believe Canon tech could not help. Tech support at most companies are non existent. They hire people in India, Philippines to talk on the phone or answer emails. These folks mean well but they do not know their product lines. They are trained to make the sale, make the sale, make the sale. Customer support does not pay anything so they do not want to do it.
