Updating never works for me. Ever. It always throws the error in the image attached.

I usually just copy the file URL from the "More Info" box and install manually but today I had 5 minutes spare so thought I would report it.

Seems to be on the very last byte. Video here: https://app.screencast.com/GMWgoK5F6BROn

That's really strange, haven't run into that one before!

Do you have any antivirus software that might be interfering here? I'm wondering if it's locking the file for a scan before it's finished writing to the disk.

Just standard Windows Defender. No third party stuff.

I tried my own code (.Net8 ) and that downloaded fine although it does say WebClient is obsolete.

Code

void Download()
        {
            // URL of the file to be downloaded
            string fileUrl = "https://www.binaryfortress.com/Data/Download/?Package=displayfusion&Beta=1&Log=301";

            // Path where the file will be saved
            string savePath = @"B:\file.zip";

            // Create a new WebClient instance
            using (WebClient client = new WebClient())
            {
                try
                {
                    // Download the file
                    client.DownloadFile(fileUrl, savePath);
                    Console.WriteLine("File downloaded successfully.");
                }
                catch (Exception ex)
                {
                    // Handle any exceptions that occur during download
                    Console.WriteLine("An error occurred: " + ex.Message);
                }
            }
        }

We're using
HttpClient.DownloadDataAsync
, could you give that a try in your code and see if you get the same error?

Did you mean to say Webclient? I can't see that method on the HttpClient and the error message does say WebClient.

I tried the following which works great too. It's a mystery.

void Download()
        {
            string fileUrl = "https://www.binaryfortress.com/Data/Download/?Package=displayfusion&Beta=1&Log=301";

            using (WebClient client = new WebClient())
            {
                try
                {
                    client.DownloadDataCompleted += Client_DownloadDataCompleted;
                    client.DownloadProgressChanged += Client_DownloadProgressChanged;
                    client.DownloadDataAsync(new Uri(fileUrl));
                }
                catch (Exception ex)
                {
                    Debug.WriteLine("An error occurred: " + ex.Message);
                }
            }
        }

        void Client_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
        {
            Debug.WriteLine($"Progress: {e.ProgressPercentage:n2}");
        }

        void Client_DownloadDataCompleted(object sender, DownloadDataCompletedEventArgs e)
        {
            System.IO.File.WriteAllBytes(@"B:\DF.exe", e.Result);
        }

Sorry yep, it's WebClient, and our dev said your code looks very similar to ours, so this is definitely a weird one! Do you get the error every time you try the DisplayFusion auto-updater?

Every single time and it has been happening for ages. It just never bothered me enough to report it. I only did it now because I was feeling unusually industrious. Normally I'm very lazy.

Never mind. I can live with it. It's nice that the message gives the the URL of the file to download. :-)

Haha all good, we haven't had anyone else report it, but we'll keep an eye out, and if I come across anything I'll be sure to let you know :)
