    I think it’s not a debugger.I downloaded it from your webside.
    The version is twainapp.win32.installer.2.0.4.msi.

    You may have found an issue. By setting an environment variable you can create a log file from the DSM that may help narrow down the issue.

    right click “My Computer” | Properties | Advanced | Environment Variables
    in “User variables for yourname”, New

    variable name: TWAINDSM_LOG
    Variable value: %temp%twain2.log

    Ok | Ok | Ok

    Run the sample TWAIN2 application to display the list of DS. Close.

    View log file.
    Start | run | %temp%twain2.log | ok

    I tested a Canon Power Shot A460 and it worked.
    Canon only supplies TWAIN drivers for Win2000 so that is where I tested. The same for the A590IS. The TWAIN driver will not install on WinXP.

    I was able to use the Sample TWAIN2 application to see and transfer images from the camera.
