I downloaded ventoy-1.1.17-linux.tar.gz, extracted it, and tried to launch VentoyGUI.x86_64. Clicking the file did nothing, so I ran chmod +x VentoyGUI.x86_64 and then sudo ./VentoyGUI.x86_64 from a terminal. The GUI opened, but the installation failed with "error occurred during installation." The web-server method failed too. The USB drive appears to work normally, since I recently used it to flash Fedora. What is the correct way to install Ventoy, and what should I check to diagnose this error?

The usual process is to extract the archive, open a terminal in the extracted directory, and run sudo ./VentoyGUI.x86_64. The GUI should ask for your administrator password. If it still reports an installation error, the message alone is not enough to identify the cause—check the terminal output or Ventoy log. The USB could still have a partition or write-protection issue even if it worked previously, so verifying the device and testing it with another tool may help.
Ventoy can also be installed from the command line instead of the GUI, but the command must target the whole USB device, not a partition. The GUI is safer for beginners because it shows the available devices. If you use the CLI, first identify the drive with a disk utility, then consult Ventoy’s included scripts or documentation and double-check the device name before confirming.
You generally should not need chmod when extracting the official tar.gz archive because the executable permissions are normally preserved. If the archive was downloaded incompletely or became corrupted, though, the program may behave strangely. Re-download it, verify the archive extracts cleanly, and try the command-line installer from the extracted directory. Be very careful to select the correct USB device, since Ventoy repartitions and formats it.
On a typical Debian-based desktop, download the archive, extract it, change into the extracted Ventoy directory, and run ./VentoyGUI.x86_64. It should request elevated privileges when it needs to partition and format the USB. The exact distribution and desktop environment matter, so include those details along with the terminal output if the installation continues to fail.
I tried launching it with sudo, but it still failed with the same installation error. The drive seems usable otherwise, so I’m not sure whether the problem is the download, the device, or my system.
