Using ftp plus compressed package update program, the compressed package downloaded to the target path, not updated error

[2099521591]

The error looks like this
An error occurred trying to start process'D:\PDF书\自动更新程序7z' with working directory'C:\Users\tan\source\repos\自动更新程序\bin\Debug\net6.0-windows10.0.19041.0'.没有应用程序与此操作的指定文件有关联。

Here's the code

AutoUpdater.Start("ftp://192.168.1.8/111//XMLFile1.xml");//检测的地址，检查xml文档中的序号与当前是否相同
AutoUpdater.DownloadPath = @"D:\PDF书"; //下载地址
var currentDirectory = new DirectoryInfo(AutoUpdater.DownloadPath);
if (currentDirectory.Parent != null)
{
AutoUpdater.InstallationPath = currentDirectory.Parent.FullName;//设置安装路径
}
AutoUpdater.ExecutablePath = @"bin/AutoUpdaterTest.exe";//可执行文件路径

It only supports zip files or installer executables for update. Are you using 7z file?

Thank you very much for solving my problem because I used 7z instead of zip
