[BUG] CreateDirectory() errorCode == 183

[PrincessLunaOfficial]

Tried to build simple application

` public class ScannerDevice { private const string DEFAULT_SOURCE = "CS 2553ci";

private readonly TwainSession twain;
private readonly ILogger<ScannerDevice> logger;  // declare a logger

public ScannerDevice(ILogger<ScannerDevice> logger) // inject logger via constructor
{
    this.logger = logger;
    twain = InitTwain();
}

private TwainSession InitTwain()
{
    var twain = new TwainSession(TWIdentity.CreateFromAssembly(DataGroups.Image, Assembly.GetExecutingAssembly()));

    twain.TransferReady += (s, e) => { logger.LogInformation("Transfer ready on thread {0}.", Thread.CurrentThread.ManagedThreadId); };

    twain.DataTransferred += (s, e) =>
    {
        if (e.NativeData != IntPtr.Zero)
        {
            logger.LogInformation("SUCCESS! Got twain data on thread {0}.", Thread.CurrentThread.ManagedThreadId);
        }
        else
        {
            logger.LogWarning("BUMMER! No twain data on thread {0}.", Thread.CurrentThread.ManagedThreadId);
        }
    };

    twain.SourceDisabled += (s, e) =>
    {
        logger.LogInformation("Source disabled on thread {0}.", Thread.CurrentThread.ManagedThreadId);
        var rc = twain.CurrentSource.Close();
        rc = twain.Close();
    };
    
    logger.LogInformation("Twain initialized");
    
    return twain;
}

public void Scan()
{
    logger.LogInformation("Getting ready to do twain stuff on thread {0}...", Thread.CurrentThread.ManagedThreadId);
    Thread.Sleep(1000);
    try
    {
        var rc = twain.Open();
    
        logger.LogInformation("Twain open");
        foreach (var s in twain)
        {
            logger.LogInformation("Twain source detected: {}", s.Name);
        }
        if (rc == ReturnCode.Success)
        {
            var hit = twain.FirstOrDefault(s => string.Equals(s.Name, DEFAULT_SOURCE));
            if (hit == null)
            {
                logger.LogWarning("The default source \"" + DEFAULT_SOURCE + "\" is not installed.");
                twain.Close();
            }
            else
            {
                logger.LogInformation("Opening {}", DEFAULT_SOURCE);

                rc = hit.Open();

                logger.LogInformation("Opened {}", DEFAULT_SOURCE);

                if (rc == ReturnCode.Success)
                {
                    logger.LogInformation("Starting capture from the default source...");
                    rc = hit.Enable(SourceEnableMode.NoUI, false, IntPtr.Zero);
                }
                else
                {
                    twain.Close();
                }
            }
        }
        else
        {
            logger.LogError("Failed to open dsm with rc={0}!", rc);
        }
    }
    catch (Exception ex)
    {
        logger.LogError("{}", ex);
    }
}

} `

When I call it using var scanner = new ScannerDevice(logger); scanner.Scan(); I get an error CreateDirectory() errorCode == 183

The lib does not have code that creates directories. Could it be the scanner driver is trying to use some temp folder and don't have permissions?

I apologize, it looks like your assumption is correct. But I have absolutely no clue what kyocera CS 2553ci tries to create and how to bypass that...
