It could be any number of the things about your system’s configuration. The most common case we’ve seen is rogue “security” software that blocks the process. The error message is communicating that the helper process that itch needs to run is not starting. I recommend checking the app logs for any clues about what might be causing it.
Logs can be found in:
- Windows:
%APPDATA%/itch/logs/itch.txt - Linux:
$XDG_CONFIG/.config/itch/logs/itch.txt - macOS:
~/Library/Application Support/itch/logs/itch.txton macOS.
