When injecting, My Roblox crashes or shows 'Unsupported Version', What's the solution? If you get this error, please make sure your antivirus has been disabled, and that you open 'DeltaInstaller.exe' instead of 'Delta.exe'. My Delta shows 'The System Cannot Find the File Specified', How do I fix that? Go to downloads (Click 'Show all') and click 'Allow dangerous file' don't worry, it's a false positive, means it's falsely detected by the firewall. How do I stop my browser from blocking the file? This is a common issue, simply turn your antivirus off in order to proceed.
